Well eventually I want to get full exhaust because I think I can pick up some nice HP since all I have is an aftermarket X. I've kind of narrowed it down to a few option but wan tto know what you would do. I already know for sure Mac LT's since I have an auto but need opinion on the rest.
1. My first option was the Mac LT's to a Dr.Gas X-Pipe to Flowmasters American Thunder Catback. Then I read that a chambered muffler like the Flows restrict HP nd people have had 4-5hp gains from replacing them with a diff catback.
2. My second option was the Mac LT's to an off road shorty Mac Prochamber to either SLP, Mac, or Flowmaster catback.
I figured I'd get better over all HP gains from the X-Pipe, and I've heard a sound clip of a car with the Dr.Gas pipe and Flows and it sounded good. Then I was thinking I'd get a better overall sound from the Prochamber but also lose a few HP. What do you all think about these combos or go ahead and reccomend a diff. one if you want. Thanks.
