991.2 GT2 RS Center Muffler Bypass X-Pipe
An A crossover pipe joining the two exhaust banks into an X shape, smoothing flow for a fuller, balanced tone. that replaces the factory GT2 RS titanium rear muffler, a part known to crack or fail with track use. Fabspeed's investment-cast X-pipe uses larger-diameter mandrel-bent T304 stainless tubing for a moderate, refined increase in sports car sound while keeping your original catalytic converters in place. It's a bullet-proof, lightweight alternative to the fragile factory titanium muffler, and stays 50-state emissions legal with no check engine light. Installation is genuinely simple, about 30 minutes with just 4 clamps, so it's easy to swap back to stock for concours events or a trade-in.
