Sorry guys for the lack of info. I am running a little 306 with a newly upgraded d1sc and a meth kit which should put me over the 500rwhp pushing 13-14lbs of boost. I won't have the money for a 4 main until next January unless I find a deal on a used 4 bolt main that is already machined. (I'm always weary about those) Since I have to redo my exhaust anyways, I figured I do 3in now (instead of getting it done later) and get a conservative tune with everything in place.
But I am worried that it might be too loud with 3in exhaust and get the unwanted attention. I am running a procharger which whines and bypass valve the vents to the atmopshere already. I would put super turbos but we already have a car with them on and I'm not really a fan of them. I am actually considering a catted x pipe to tone it down a little or running a basasni tip with the baffle from time to time. But man, I have this gut feeling when it comes time to make the decision I am just going to say screw it and run it how it was meant to be. LT + O/R X + straight through resonators/muffler = how it was meant to be.
