Akrapovič BMW M2C/M3/M4 (F8X) Downpipes
The Downpipe (Stainless Steel) was rigorously tested and developed alongside the Evolution Line (Titanium) system.
For those seeking the ultimate in weight reduction, tuning potential, and racing sound, Akrapovič offers stainless steel, cat-less downpipes that transform the BMW into an even more powerful machine. This setup is designed for dedicated track-day cars and enthusiasts, enhancing the overall experience of what is already a high-performance vehicle. These meticulously crafted downpipes deliver exceptional sound quality without introducing unwanted cabin noise, making them an ideal upgrade to Akrapovič’s Evolution exhaust system.
Please note that when installing Akrapovič aftermarket optional downpipes, which are specifically developed for use on closed tracks only, remapping the ECU is mandatory to prevent potential “check engine light” warning signals.
IMPORTANT: THIS PRODUCT DOES NOT MEET EMISSION COMPLIANCE REQUIREMENTS FOR STREET OR HIGHWAY USE.
