Yes I already have an h-pipe resonator delete. If you got to American muscle website they have a nice video. This is the RTR system, which is made by magnaflow exclusive for RTR. A lil different but similar to the MF street system.
Jay,
Thank you for your input, I hadn't seen the RTR products. Looking at the pictures, the street and performance look the same on the outside. I wonder if the RTR Competition is as loud as the Magnaflow Competition?
