Built to meet World of Outlaws, All Star, ASCS, and SUPRA specifications, it delivers the unrestricted flow you need while keeping your rig legal at every event. The 3.5-inch inlet and outlet sizing pairs proven muffler geometry with straightforward bolt-on installation, so you can focus on setup and performance rather than regulatory headaches.
