Nice! A dedicated exh sys w/crossover is something we needed. 3" pipes should easily support big block power.

I like it!

Ooops. Well 2.25 " should work well enough.

Nice setup, the 60's will be quite quiet, good for cruising. I think you should have built it with at least 2 1/2" tubing though....

Does anyone have a comparison to the Flowmaster and Magnaflow 16710?
