right after i put long tubes on, nothing else, sounds ****ing retarded about like 1500 rpm, and will make you deaf at like 3k or hard acceleration.
mac long tubes, 2.5 pipe to hacked up borla mufflers, sounds like **** imo, going to redo my entire exhaust at some point. (no cats) imo cats make it sound less raspy
fast forward to the end, and thats a 4.2l stroked h/c/i 10 psi of boost with long tubes, 2.5 piping, hacked up borla muffs. Sounded like a god damn air plane.
