I am now running with MAC 1 5/8" long tubes, 2 1/2" Pro Chamber, and 2 1/2" cat-back. The rest of my engine is completely stock. I noticed a HUGE increase in power and feel that even the low end torque is a lot better than it was.

I know now that my exhaust was what was causing my problem with me losing all my power by 4500rpm, but still... this thing is a beast now! It climbs hard from launch all the way to 6000rpm (what's the stock rev limiter set at?).

Definately go ahead and get 1 5/8". I love mine, and I bet when I install my GT-40 intake and ported stock heads this exhaust will make an even bigger difference.
