I'm about to buy some Dynomax Bullet race mufflers and have them installed along with 2.5" piping. How much would an average exhaust shop charge for this kind of work? How much have you guys paid? Is it cheaper just to buy a cat-back kit that's already put together, like Flowmasters or something? I'll also be installing a Mac Prochamber at the same time. Hopefully the car will sound real mean.

. I too have a Pro-Chamber with Dynomax super turbo's, and I think it sounds good, but it is WAY too quiet. I'll switch over to the Ultra-flow's or Bullet race mufflers eventually....
