Lowering stock exhaust

I wanted to see if anyone has attempted to lower the stock exhaust can. The reason I want to do that is because I am trying to find a way to lower the passenger footpegs so that my wife can stand to be on the bike for more than 30 minutes at a time.

A few years back I bought the Verholen 60MM lowering kit. It clears the exhaust can by sticking out about 1.5 inches on the right side and according to my wife it is awkward and throws off her balance. So it came off the bike quickly. Now I want to revisit it. I was thinking to try to lower the exhaust by 1-2 inches, remove the outward spacer from the right Venhoven extension piece so that the footpeg is above the exhaust, rather than to the right of it.

Has anyone tried to lower the stock exhaust?

Also I looked at aftermarket slip-on exhausts and they all seem to be about the same thickness as the stock. Is there anything out there that will fit the K1300s that is substantially skinnier?

Any ideas and suggestions will be greatly appreciated.

Re: Lowering stock exhaust

This is the thinnest exhaust I’ve ever seen...the fitment shown is for the K13R, but this will also fit the K13S. Nice exhaust, well made and doesn’t break the bank.

Re: Lowering stock exhaust

Good luck with your project... My wife had the same issues on my K1200S...

I tried 2 different seats.. tried the lowered pegs. added a backrest.. even got her drunk.. Nothing I did (no matter how costly) made any difference... As I couldn't solve the problem.. she never rode with me again. that was 12 years ago...

Re: Lowering stock exhaust

I think it would be easier to find a used Remus Hexcone exhaust. They are substantially thinner than stock (besides being lighter). If you leave the insert in place they are not much louder than stock. If you remove it, it is healthy and 5 more hp on the dyno but not loud in my book.

Re: Lowering stock exhaust

lowering the exhaust is super easy. When I got my 07 k12r sport [without the stock bmw bags], i wanted to add soft bags, same size on both sides.
the muffler has a ball swivel joint that allows the muffler to swing out for tire changes.
I simply added a 3" long aluminum plate to drop the muffler to the same height as on the k12gt and re tightened the clamp.

It looked so good in the lower position, that I left it there after obtaining and adding factory bags. Plenty of room for lowering the foot peg as much as 3".

The factory bags came from Tim [cabnfvr] after his crash in Kentucky. Thanks again, Tim.

Here is a pic of stock and lowered position, very subtle change:

Re: Lowering stock exhaust

Good plan, I forgot about the spherical joint! My excuse is inside the thread "Graying of Daytona".

Re: Lowering stock exhaust

Thank you all for the input. Yes, it is super easy to lower the exhaust because of the spherical swivel joint as I discovered. I test fitted the Venhoven adapters. The footpegs are about 2 inches lower than stock with room to go even lower if needed. I hope this does the trick so I don't have to trade in the K13 in for a GS
