When capped, cutouts allow exhaust to flow through your mufflers Uncapped at the track, exhaust exits before the mufflers for a straight-pipe, no-muffler sound Allows you to use a quieter stock-type muffler while still maximizing exhaust flow when you need it Leak-free seal with high-temperature gasket and heavy-duty block-off plate. Precision plasma-cut opening. Mig-wielded construction. Wing nuts provide easier tool-free removal. For off-road use only. Welding may be required.
