Who says you can't have style and performance together. Check out this dual rear axle back kit for the JK Wrangler, Rubicon and Unlimited. You even have your choice of T-409 stainless steel or heavy duty aluminized construction which both come complete with mirror polished T-304 stainless steel tip. And for those who love that 'murdered out' look you can get this system in MBRP's high heat resistant black finish. No matter which you bolt onto your JK you will see better than 22% improvement in exhaust flow over stock, very important if you are running additional performance mods. Of course, you can always count on MBRP's 'fits right the first time' quality, great sound and an exhaust that's built to last.
