Any feedback from Vibrant customers? I need a catback for SCCA D-Stock SOLO II. Don't want to go 3", 'cuz right now it's catback and drop in filter only. Want to go 2.5 at least though, 'cuz next year will be STX and I can get a header, CAI, and HP Tuners.

Want the absolute best midrange power possible. DON'T want loud. Quieter the better, but a nice tone would be good.

You're getting more torque from the restrictive muffler holding up the exhaust, but you're killing your hp from the restrictive as hell stock muffler

I just got the Vibrant header/dP combo. I am going to pick up the Thermal. Vibrant cat back is 3.0 so it might be a little loud
