If you go to Nitrous.com I think Pete has his Flowmasters on in the beginning of the web page. But I'm not 100% sure, but it sounds just like mine on that site and we have the same style system. Longtubes, h-pipe, 3" flows
This poll can't be too accurate since you didn't include "Whomever's X-Pipe & Catback" combined. Just look at the cat-back versus x-pipe: Magnaflow is winning the catback, yet Bassani is winning the x-pipe contest. Like that makes a lot of sense!
I just came from having my Magnaflow X-pipe (no cats) and Magnaflow Cat Back installed and let me just say that I will never shut my car off again. After years of owning imports I know how an exhaust should sound. This thing sounds amazing and I'll be hitting the dyno this weekend to hopefully improve on my previous 410 RWHP/460 TQ.
