I just got my factory exhaust straight piped
. Sounds great, but I'm all stock so I can't see spending the money for a 4" turbo back. Does it really make that big a difference over the 3 1/2"?
Anyway, short story long, I asked the guy if adding a tip would help the sound and all he could do was grin. He started walking to a rack and I was curious so I followed. We got there and he pulled out an 8" tip!!! I could fit my entire head in that thing! Might as well weld up a hot water heater.
I didn't get it because my truck is still at factory height and I don't want it dragging the ground. That thing was HUGE!
