Straight pipe. My mechanic was saying your going to get very little horsepower from a cat back so just put a hi flo resonator and take out the muffler.

you don't make much from a exhaust to begin w/ but i did 2.5" cat back to a single in/out flow master... it make 5whp/11lbs on my 1.8t... the DP(header) will make cars more power normally
