I bought the  universal magnaflow performance  turbo mufflers took them to my shop and had them swap out stock mufflers for these. Kept tge 3rd cat and resonator. Not real happy. Has a deeper bassier tone at idle but every other way sounds very quiet. Probably as quiet as stock.what gives? Doesnt sound anything like the youtube clips.

replacing the resonator with an x-pipe may help

You can remove both but you will have some unpleasant (Rasp)to deal with IMO,just delete the 3rd cat and put a 2.5 in x-pipe,the true bottleneck are the DP.  Z
