I would go with PYPES. They are a sponsor on this board and have a NICE 2.5" mandrel system, X pipe and race mufflers for $487 USD. Thats stainless steel also. Headers, either hooker super comps if you have a big motor or Hedman Elite if you are running a 350 or mild 383.

If you have a relatively stock engine, the tri-Y design header will give you a seat-of-the-pants torque boost up to approx 5,000-5,500 rpm. After that you are better off with the 4 tube equal length design. STAN'S HEADERS in Washington State makes the best tri-Y design. Search Stan's on the forum for testimonials.

That might be true, I just saw Spring 07. I emailed them about building me a 3" mandrel, x pipe with their race mufflers and they said they didn't think 3" would fit well without rubbing on everything.
I just wonder how much it hurts power going from 3" mandrel to 2.5" mandrel on a 500hp motor.
