looking for a good exhaust system
Eugene I believed you asked about results for an M&M system with 200 cell cats.
Below is a 997.1 GT3RS dyno graphs:
Stock vs. M&M headers (a generation older) with 200 cell cats, side muffler delete and M&M center section.
Yielded a peak 20 whp gain. Not shown but after a GIAC tune another 10 whp was gained for 393 whp.
The current new M&M headers are better.

Hi Eddie
Lets do a package deal with ECU and exhaust.
If catless and its about 105db I'm in for catless+tune. If its over I'll settle for the 200 cell setup.
Still thinking Ti or SS

Eugene, I would say that 105 is pretty close it's between 105-110 max ... It's up to you.
Please send me an email and I'll prepare the package for you. I'll take care of you on the package.
Tks,
Eddie.
