Based on two cars locally, owned by friends of mine, run one of those two Magnaflow mufflers and replace your stock resonator with a 12" Vibrant resonator. It's not thundering loud like it will be with no resonator, but it's louder than with the stock one. Sounds really great on the car, pretty much ideal.

 

Best exhaust? Total silence, IMO. I used to like Magnaflow.

 

I wish my car was silent still, I like the look of my Magnaflow 14816 and luckily it's not very loud, it's actually a pretty nice exhaust note, I just wish my car had the power to back it up.
