I had installed turbo bumper to C2 so narrow bodys muffler tips don't fit anymore.
Though now my muffler is welded to fit, want to exchange it for other muffler.
It seems C4S's muffler is the same as C2's, right?
Is there a adapter that connect C2's muffler exit to turbo bumper exit?
Please teach me ,anyone!

 

I am doing the same mod. I have had the bumper for a year now and am finally getting to the install. I am attempting to use the J pipes off of a C4s exhaust attached to a c2 muffler to position the tips properly. The j pies are the only difference I am able to see between the C2 and C4s exhaust. If this works it will allow for fitment of any aftermarket exhaust designed for the C2.
