This brings our proven single mid-pipe expertise from the F8X M cars to the G8X platform — an excellent alternative to our equal-length X-Pipe mid-pipe.\u003c\/p\u003e\n\u003cp\u003eIt delivers a slightly deeper tone at a similar price point, without secondary cats. While the G80\/G82 M cars receive high praise for performance, many owners find the factory exhaust too muffled. This mid-pipe, combined with our full exhaust system (downpipes + valved axle-back), restores the true BMW M-car growl you expect.\u003c\/p\u003e\n\u003cp\u003eBolt-on design requires only a single cut to the stock mid-pipe. Compatible with most aftermarket exhausts\/mufflers.
