Need some Exhaust advice ASAP!!
Holy ****!

sounds amazing! haha..so what exactly is it..pacesetter longtubes, tsp o/r Y pipe cut with a flowmaster merge welded in, and a 4 inch mufflex catback? What was your old setup as well? Pacesetters, tsp 3 inch duals with dynomax bullets?

i'll soon be going to PRC heads, ms3, FAST 102, and TSP 1 7/8 through the same Y and cat back. and MAYBE a 4" cut out if i'm feeling randy 
and to answer your questions, yes to all.

As far as catbacks, i just got rid of my magnaflow for a TSP duals with dynomax bullets dumped. I would go with the hooker catback, or GMMG (if u got the money) or duals.
true duals OR 3.5" or bigger Y-pipe/cat back. and basically mufflex is the only one i know of that makes big diameter cat backs for our cars.
