Exhaust System
Ok i really need help with this decision, i've heard alot of specualtion about axle back exhausts for the xd and how they are more ideal and preferred over a full cat-back system. im stuck between the magnaflow cat-back and the precision muffler axleback, i need numbers quick...a cat'back for the tc claims 6hp and 7lbs of torque...can we expect the same result for our car or will it still be ideal to just get an axleback and again what are the hp and trq gains from that, i've heard strup dyno proved there axleback to 6hp...how true that is idk but again im just lookin for some further information.
