stock we have 2.5," most aftermarket are 3" and they don't add much, most tuners (from what i hear) add like 5whp.

Hahn has dyno charts on their site. It is one of the best exhaust for adding power, compared to others. You can expect 12-20 HP from a 3" exhaust on the SS

^^ I think you guys are a great sponsor and Hahn may claim that much but its been proven over and over again how little horsepower a catback will give the LNF. Now, for sound and quality, Hahn would be a good option.
