How I made my Custom Exhaust for Paso 907ie
Posted: Wed Jun 18, 2008 8:38 pm
Hi Guys, Some of you have asked me for more details about my custom exhaust so I have put together some of the details for you. First, what inspired me to build my exhaust was a desire for the best sounding most exotic looking Paso I could dream up without severely changing the lines of the original beautiful design. In 1995 I saw the original 916 and like everyone else that laid eyes on this bike fell in love with the high under seat exhaust. This gave me the idea to start designing a similar look for my 907 without changing the tail section and rear frame. Once I started the design was easier than I thought and cost me no more or even less than the best systems available from the aftermarket. For me, I think I have achieved the perfect look to finish off the Paso and the sound and performance is completely tunable with the SuperTrapp mufflers.

The build details:
All parts Tig welded by me
SuperTrapp 4” conical muffler with 2” inlet and 2” outlet core 18” muffler body from in to out
Muffler’s hung from original alloy turn signal bracket at rear
304T Stainless Custom S mid pipe with 1.75” inlet from header pipes that flares into 2” pipe
Each mid pipe has (1) 45 degree elbow and (1) 90 degree elbow to complete high pipe bends
Mufflers are spaced 1.5” from bodywork
8MM spacing between pipe and swing arm on both sides
Passenger pegs received 1.5” Stainless spacer to keep WIFE happy (very important)
Muffler bodies at the rear are 8” apart under license plate
Muffler cores are 10” apart
Center stand bolts on with no interference


Currently, I run the pipes without the end caps and they are not too loud at all. If I want a more quiet exhaust I insert the plate and let the disks do their job. I carry the end caps under my seat in case I need to install them. By having disks at the end of the muffler and no end cap the sound gets more raspy. 12 disks open is what I like the best. I found this setup to work very well, sound is excellent and I cannot drag any parts in really twisty aggressive riding.


Best of all, I have never seen another Paso exhaust like it and all for less than the cost of an after market maker.
Use this link to check a bunch of photos that I have taken of the exhaust so you may see from every angle how it is put together.
