I've ordered a APEXi N1 muffler, with 2.5 inlet, T-306 stainless steel exhaust - blah blah blah....anyways, it should be here next tuesday!, I think I plan on getting new piping and...I am dumb-founded on what else I should get? high flo cat..what!!? please somebody help me!

 

Do you have a cold air intake? Might be worth looking into. Breathing easier on both ends always helps.

 

nono, I plan on doing that later - im talking about exhaust, high flo cat and piping and alll of that or whatever....
