I just finished installing JBA headers, Cajunbpipes and JBA cat back with ultra quiet resonator. The support and customer service I received from Jeff on the headers, bpipes and cat back were top notch. Joe provided outstanding support with the uprev install and answered all my questions very quickly. I was in a bit of a hurry to get the job done so we could leave for our family vacation. The quick response by both of these guys made it possible. As far as the parts are concerned I couldn't be happier. The armada is my wife's daily driver/kid transporter. We didn't want an overly loud setup, but wanted a permanent fix for the exhaust manifold issue. This is by far the best way to go. If you are considering this upgrade Jeff and Joe are the guys to call.
