The optimized primary tubing ensures a superior fit with performance benefits that you can feel.

    Advanced Installation. This kit includes all the necessary installation hardware and parts needed for a seamless process that requires no welding.

        Are these high flow cats and will they help quit the cold start over a cat less header? I have the Corsa extreme exhaust and I don't feel like purchasing another exhaust system even though I know they will still be loud. Thanks again.

        • Yes, any catalytic converters sold on our site will be high flow cats unless otherwise specified. High flows will help muffle the sound a bit, however they are still almost as aggressive as a catless Mustang.

        Does this system come with the O2 sensor wire extensions or do they need to be purchased separately. I did not see them listed with the kit. The previous listed system came with them. Thanks for the help.
