I have a '14 VQ37 currently set up with a Rev9 Axleback "muffler delete". I'd like it a bit louder, and instead of doing a full resonator delete (gross!) I was thinking of replacing the stock resonators with Flowmaster FlowFX. Was wondering if anyone has a similar setup, or can point me in a better direction? Test Pipes and Muffler delete apparently sounds like crap, otherwise I would consider going that way.
