Make that another vote for the Roush Axle-back! If you want aggressive, the Roush exhaust will give you the perfect tone with a factory mid-pipe IMO. Plus cost isn't killer compared to others!

Had gt500s for a year ... Thought it was good.

Borla s types now. No comparison. Borla ftw.

 

The Roush is LOUD. Maybe with the resonators still in place it is ok. When I had them it was loud as hell. I liked it, but it gets old. In the same basic volume camp as the GT500, but generally nicer and deeper, the JBA exhaust is a great value. I have them now (and I have had tons of systems), and I think they are a great combination of tone, volume and aesthetics. Don't let the picture JBA uses fool you. They are semi-polished stainless with a 4 inch double wall slash cut tip. They are much nicer in person than the picture presents. Much better looking than GT500s as well.
