RE: Composite Sukhoi
BTW I sell the Evo 58s.
For a muffler Bisson is making a good one, but I'm not sure if it will all fit in the cowl because of the squarish nature of the can and the round cowl.
A side mount seems to be the easiest to use, Ithink Bisson makes one of these too. I used a side mount bisson with my G62 and it worked well.
