Hi
I have the Adventure 2 pipe that was designed for a BMW F650GS.
This week end, the bolts holding the baffles and internal end cap worked their way loose and all fell out. It also cracked the end pipe. I need to know what size the bolts are so I can replace it, and wonder if you have anyone in south africa who would supply the end cap...
Many thanks
Steve

Adventure utilizes our "SuperLight Stainless" Series Universal mufflers which uses 4" discs. The stainless steel allen head screws used to secure the disc assembly are 10-24's and can be purchased in a 6 pack under P/N 404-7206. The stainless steel "closed" end-cap used at the end of the disc assembly can be purchased under P/N 406-3046.
A good source for these components would be Summit Racing;

I have the same exhaust on my BMW F650GS and want to replace it. Do I order P/N 425-17560 or 425-17190? I got a little confused because the canister itself is 16" but the overall length from inlet to the turndown outlet is just under 19".

Which one? :confused:

The 16' & 19" reference is for the "can" only, the inlet adaptor adds another 3.5-4", plus another couple inches for the turndown end-cap.

Thanks for the reply!

I went to the Summit Racing website and this is the info they have on P/N 425-17560 which led to my confusion about which one to order. The information they have on the 16" version states that the overall length is 16" not just the length of the can.

Case Shape Round
Inlet Diameter (in) 1.750 in.
Inlet Quantity Single
Inlet Location Center
Outlet Diameter (in) 1.750 in.
Outlet Quantity Single
Outlet Location Center
Internal Construction Baffled and glass wrap
Muffler Material Stainless steel
Muffler Finish Brushed
Case Length (in) 13.000 in.
Case Outside Dia. (in) 4.000 in.
Overall Length (in) 16.000 in.
Outlet Style Turndown
Quantity Sold individually.
Notes Internal disc-style muffler.

Still kinda confused and need to order the replacement to get my bike back on the road...

Does that mean the information as listed by Summit Racing is incorrect?

What you have highlighted in "red" is incorrect.

Thanks for clearing that up for me...:D
Now I can get it replaced and get the bike back on the road.

07 Yamaha Vmax was purchased with the supertrapp exhaust, need to replace a few of the bolts that hold the end cap and the 8 disc per side in place.

If I remove 4 dices per side will this make it have a deeper tone or is there better way to achieve this kind of sound?

Removing discs may provide a slightly deeper tone; however it may be at the sacrifice of top end performance.
