I wanted to do the exhaust system on my srt. I want to do a catback sustem with 3' piping with dual apexi n1 style mufflers. Or i can do the same setup but with dual tips instead of the mufflers. I want to aquire the nice deep turbo sound out of the car. Also, will this setups yield any gains taking into consideration that im putting 3' pipes. I live in Miami and i have heard that Castellano mufflers and Miami Mufflers are the best places so far. Anyone with this two setups that can post pics or dynos to see if they yield gains. Also, pics are apreciated.
