Dinan High Flow X-Pipe - 2015-2020 BMW M3/M4
The Dinan X-Pipe removes the factory center section after the secondary catalytic converters, including the large resonator. In its place Dinan introduces straight through mandrel bent 2.75" T304 stainless steel tubing and the custom 'X' for better flow, and an improved throaty sound. In addition, the kit comes complete with mounting hardware, OE quality clamps, and flanges, for simplified installation.
NOTE: Since a resonator is deleted there is potential for increased cabin noise associated with the Dinan High Flow X-Pipe. Please consult the media in the 'PicturesVideo' tab for a representative video to determine if the product is right for you.
Processing & Shipping Overview
Processing occurs before shipping.
Most in-stock items typically process within 2–3 business days before shipment or pickup. Expedited shipping options affect transit time after an order ships and do not speed up processing.
Made-to-order, special-order, vendor drop-ship, and freight items require additional processing time before shipping. Any extended lead times will be noted on the product page when applicable.
