k1300R/S OEM EXHAUST MODIFICATION - HOW TO

Hi Guys

I like to see well exposed the rear Wheel of Fiona, is for that I made a new exhaust OEM based, jut to see what happens, looking for the look, sound, weight and reduced temperature.

Also I like to have the bike as original, I've searching for a used exhaust, fortunately found one on eBay, bad, dented, scratched, burned, but perfect for my objective, $69 plus $ 90 for delivery + 50% country taxes, nothing compared with de OEM, in US cost $1300.



before cut it, I did a search of how is inside. Found this scheme in the Ricardo's Page, is not equal but gave me the idea about how to cut the muffler



I drawed 2 lines to cut, one close to the front welding and the second close (40 mm. approx.)to the clamp, just in case I screw up the line.




Cut the external stainless Steel shield - surprisingly a good thickness (0.80 mm), and internal shield separated with asbestos (? ) )




The front part with catalizer



Separate the catalizer making a cut just in the border of the Weld line



At this point there are these parts:



In the rear part I have to cut both pipes because now there are interference with the front, then I've grinded both tubes close to the welded line



At this point I mounted the exhaust on the bike using the second bracket to join the two parts, I rode few minutes. The first backfire separate the parts, showing a great pressure into the first chamber, then I made ​​several holes (10 mm.). to relieve the pressure, trying to orient directly toward the end tube, in this way the gases goes trough the 2 tubes to the second chamber and part directly to the exit.



sanding and polishing exhaust scratches:



sanding, polishing and mounting the clamp. Is necessary to put some thread locker like Loctite for threads



Welding: I didn't have the necessary equipment so I asked to a welder guy (loves bikes!) He works in a factory for milk packaging machines, stainless steel products specialists. He did an excellent job for only $ 40.

After welding, full polishing




Now the simple task to install the exhaust on Fiona



END OF JOB :


As result:

- I Keep my new OEM exhaust
- From more than 6 Kg. To less than 4 Kg
- less temperature, and it cools in less time
- Objective achieved: Have the rear Wheel with mini-skirt

Sound is like Louis Amstrong muted trumpet, not loud between iddle to 2K, excellent to ride in town, and amazing roar when opens the butterfly. I promess a sound clip here when have a bit of time.

Open to questions, critics, kiss and slaps

Re: k1300R/S OEM EXHAUST MODIFICATION - HOW TO

Amazing job, very nice looking result.

However if there is asbestos in there (I would hope that it is some sort of silica based insulation) I would not recommend that anyone attempt this. I spent a number of years working in the power generation industry managing asbestos removal projects and have seen the results of exposure first hand. For sensitive people even a few fibers can spell serious health consequences (death) 20 years down the road. It takes a professional to know how to properly handle and dispose of the stuff.

Bernardo wrote in is write up that he thought there was, Asbestos is still used in Germany so it is possible. However it is more likely a silica product. You can't tell by just looking at it

Yes, your'e right, is really dangerous, perhaps is not asbestos, and only seems that, The exhaust was made in Italy and there are strict laws about asbestos same as the rest of Europe.

Just few minutes with a mouth protector

20 years? oh sh*t will be 83..... I need to take care, if not, when I grow up can have some problem...

I did the same type job on my 06 VFR ! The cans were not as packed with SHUFF . A real simple job without a ton of effort .

So it stayed OEM ... well

The V4 makes an awesome sound on the Honda .... After this mod ... WOW it sounded REAL Awesome at anything above idle .

Very, very nice work and well thought out. Can we see a photo taken of the side view of the motorcycle?

Just an additional idea for consideration. My problem with the stock system was that the can was the only chrome item in view and drew the eye away from the lines of the cycle. I sent my muffler to Jet Hot Coating and had it coated in satin black to better match the other components.

Agree with you, brilliant is not for our bikes, I considered to sand blast the Surface but the problem is when get dirty is very difficult to remove, only sand blasting again, not practical. Are you jet coat the muffler?, worth?, is truly difficult to paint stainless Steel adding the high temperature. Then I decided to let as it

Thanks for the photos. Very nice work and a major improvement.

Jet Hot is a well known company in performance circles here in the States. They do a lot of auto and aviation coatings. They offer a range of colors and textures. I can't vouch for the long term durability on a cycle, but the coating is excellent on auto headers. Check with some of the auto racers in your area to see who does ceramic coatings and to check the quality of their work.

I can see a shortage of stock silencers in the future. Excellent job. Your local chrome shop can do the polishing for those who don't have the equipment. Good work.

Great Job Bernado. The mod looks great. I don't have the skills you do otherwise I would look for a bent original exhaust myself. (Bugga) I agree it shows off the back wheel beutifully.

Good job

Hey Bernardo Did you consider bead blasting. Nowhere near as abrasive as sandblasting and puts a nice matt finish on the surface.

Yes, we call here shot peening with spheres, is a good process

Seems the problem is when gets dirty and becomes Brown due the heat, is difficult to maintain clean and matt. I'm testing if the exhaust becomes Brown or maintains bright, after that I hope an idea will appear

Today I rode 600Km with a good throttle and continue shinning, sign of less temperature. Will see.

Thanks bobby.
Bmw can't do this because they need to follow contamination and sound regulations. Good bussiness for the aftermarket exhausts brands...

Re: k1300R/S OEM EXHAUST MODIFICATION - HOW TO

Bernardo, that looks fantastic. I think I'll start shopping for a spare can and try the same thing. I was also considering the jet hot coating for my K13R, I decided to try barbecue paint just to see how it looked, and surprisingly after a few heat cycles it has become quite tough and durable. But I think I may spend the extra $ on a shorty and get it done properly.

Hi Skapan!

Here there aren't ceramic coating like suggested by KPV above, I would like to see the results of that job, just in case you try

After the time the exhaust will be like the exhaust pipes, dark brown but uneven Must be something durable and clean.

Perhaps I'll try to sand blast in the internal zone (close to tyre ) of the shortie, to see what happens, after all is not visible there.

I like the evolution of the original idea!

Guess what I just started cutting with the 4KW laser at work?

Thanks Bernardo, will post final pic's as well

Cool!, not for shy guys...

With laser you'll get more precisión.

Re: k1300R/S OEM EXHAUST MODIFICATION - HOW TO

Laser just make less polishing work for me, since it will cut a straight line every time.

We have a tig at work as well, and I'm good with it

However my main interest in doing this is the cat, it gets too damn hot, melted my wife's boots once.

I don't think I will cut as much as you did, I want to leave an expansion chamber right after exhaust exit, as any tuned exhaust should.

Will likely 3D model it, will share file when I'm done, so others can flow model as well.

This sure beats buying another pipe, as I liked the looks much better, and I can be sure it's "right"

Re: k1300R/S OEM EXHAUST MODIFICATION - HOW TO

A few things of note, now that mine is apart.
The back plate, where you drilled, is VERY curved, hard to tell from your photo.

It is clearly designed to help form / maintain / extend standing waves.

A hole in the center would likely be better then several small ones.

Based on volume alone, 80mm would be the amount you want to remove from pipe length, to keep same wave dynamics. However I will CFD this pipe as best I can.

Problem is I'm not 100% sure what's inside second half, will need a probe scope for that.

The inner shell, is not welded in the front, in is supported with a flange, the sits inside the step you see in your photo, I need to work out if I need to support it again. You took enough off so it is likely not a concern.

Yes, is curve, reason is to increase the volume in the first chamber, maintaining linearity with the external clamp.

Quote:

How can we know that...

Quote:

Perhaps would be good, also I drilled directly to the final pipe, may be is not necessary and could change the sound. More grave.

Quote:

Easy, you can search with a steel wire, but you have 2 pipes direct to second chamber, and the 3rd pipe is that you can see at rear. also if the 2 pipes are welded to the first chamber wall, I'm sure there are welded between 3 tubes in the second chamber.

I suggest let it as original, no place to move when you finish the work

Re: k1300R/S OEM EXHAUST MODIFICATION - HOW TO

Why else would you make it curved?
They went to extra expense for something, unlikely it was structural ?

Could be for wave dynamics in second half, but given, it is right in the middle of the cat pipe....I suggest I'm right.

Clearly this pipe is based on CFD models, so I will do the same.

*Note there are two schools, on if anything past collector has an effect. Many say no, but anyone with a supertrap suggests different. From experience, I believe the later

Sorry Dan, I miss your post...

There are 2 reasons IMO,
To bring enough place to gases at the exit of catalizer
To let dilatation, If not, the separator will force the external layer pushing the clamp and deforms the external layer

It's going to be awhile, Wife transmission imploded, 3000 KM outside warranty (piece of shit Chrysler).

I need to rebuild it first, then finish some extra design work I took on.

Re: k1300R/S OEM EXHAUST MODIFICATION - HOW TO

Ok it's spring, had to finish this off.

First off, my goal here was not to make a "shorty", I simply wanted to remove the cat, and keep my current performance. I am happy with the stock pipe, just not how hot the cat makes it.

After cutting off the cap, I CFD'd the whole pipe, to get as close to stock as I could.
I drew my own conclusion, after seeing what the flow looked like in the computer, and determined removing 65-75mm was as close as I would get to pre-cut out.

I removed 70mm total, leaving a flange of 13mm (see attached)

I polished the cap before welding, as it saves time afterwards.

First fit was pretty nice, had to show off here, I was impressed for not pipe fitting in years (I am an engineer after all)

You can get an idea of the size of the first chamber, after fitting, from attached pics, very close to stock.

I'll let you all know how it works, in 2-3 weeks, as snow is just leaving now.

Well that was a waste of time, it still gets stupid hot, even without the cat.

Friend has a Leo Vince pipe, you can leave your hand on it, after a full run, nice sound as well. Should have mine Wednesday

Re: k1300R/S OEM EXHAUST MODIFICATION - HOW TO

Is logical, is an exhaust, if you don't have air chamber between the exhaust and your hand by sure you burn your hand.

Catalyst heats the system but is not alone, you have a wide first chamber in contact with the external wall, separated and isolated, but not for maintain cold the external side
Also you didn't touched the intermediate internal wall to let gases flows easily to the second chamber.

If you remove the cat, it lets the system get cold faster, but not cools the system

I can say right now, after 5.000 Km, temperature difference is noticeable, today the exhaust isn't brownie, and remain the shine, good sign of less temperature.

But if you don't like is ok, after all you have tools and sophisticated machines to do the job for free

Not my first bike by any means, but it is the first bike that will melt your shoe if you touch the pipe.

Even worse for my wife, during the rare times she rides with me.

All they need to do was increase the insulation and space between the inner and outer walls, but then again it's already heavy as hell.

Bad design overall IMHO

Update of the Shorty

- After 10.000 Km.
- No issues, no cracks, shape as the 1st. day
- Definitely less temperature, Usually I've polished the "Brown" exhaust every 10.000Km to maintain it shinny, now as you can see in this pic, is still brilliant and only on the rear becomes brownish.
Next:
- Clean and polish.
- I'll try a sand blasting just to see how look like, perhaps I'll try a BMW logo. I'll see.

Hi Bernardo, would you do anything different if you were to do it again?
I have finally purchased a second oem exhaust and want to do the same mod.
Question on your weld job, how did you get it to look as if it is factory? And is there anything I need to be aware of when I do this?

Hi Jos

Good one! Now start the surgery !

I think not, works fine, sounds good, engine seems to work better, may be is only what I feel... That's ok.

I'm a lucky man to find the right person 25 Km. from my house, is a craftsman welder who loves motorcycles, But I bet you can find a good stainless steel welder.


Quote:

Only be careful with the material inside the muffler, I don't know if it's asbestos, just use a mask.

Another: Be aware from the throttle! specially if there are cops near, is quite adictive

The exhaust is in transit.

There is a welding shop here in town. They did the welding for my RR exhaust mod. I'll probably go see them again.
I do have a welder myself but my welding has a few things to be desired lol

Let you know how it turns out.

Re: k1300R/S OEM EXHAUST MODIFICATION - HOW TO

My attempt at the Bernardo OEM exhaust project started today.
The first cuts have been made, I run out of time but the only thing left to do is drill the holes for pressure relieve and a little cleaning up of the edges.



Going to see my welding guy next week.

Perfect!

A clean cut, just on the inner wall, now you can test the welding on the part that you don't use.

Good job

Excellent! , really light isn't it ?

Why you need a hanger?, don't you have the original clamp?

I removed the passenger footpeg brackets. The bracket also serves as a hanger for the exhaust.
I will work on it tomorrow.

Hi B


Perhaps you can buy for few bucks a K13 exhaust... is interchangeable with your K12

Look at this thread: http://jcsthemetalshop.blogspot.com....mation-on.html

Interesting post.
But right now there are no cheap used K13S cans on ebay, but several K12S cans.
