uppipe downpipe with stock catback
I'm currently running a helix up dp and a stock catback(minus some cats of course). Would an after market cat back make much of a difference over my stock muffler and resonater? I want to look as stock as possible, defenitely a quiet twintip if i have to.

Yes because the pipes are usually 3 inches with no cats instead of the stock 2.5 inch so it will make a difference. If you want it to look stock and quiet then a lot of people like the borla hush. Also look at the vishnu, may be a bit louder but still nice.
