Well got my full system today and I love it. Looks and sounds SICK> I cant wait to dyno it. Im guessing its gonna make about 3whp peak and killer bottom end power and torque. I got the upgraded black can, black turndown(I hate the euro tip), and quiet core. Quiet core is a nice piece. The headpipe starts 1/8 smaller than stock and were it goes into the can its 1/8 bigger and the can steps up another time at the inlet and again 4inches in the can. So i bet its gonna be big bottom and mid. Here are a few pics and a sound clip.
These pics show the cool angle they put on it. Same as the ct and dasa system. I like it alot.
This shows the major restriction in the stock headpipe. Ouch.
This is a little clip for you guys. Enjoy
