It's got LeoVince SBK slip-on cans, so it's already got that mean growl. Sounds like a Mustang 5.0 when it takes off. I love it! The guy I bought it from also added the lower plastic, a fender eliminator, Zero Gravity screen, K&N filters, rear seat cover, and a PCIII usb.Brownie - Wait til you add some exhaust. Sounds like a friggin V8!! LOL!
