Boost Logic M8 Downpipes These downpipes can be ran with stock secondary pipes which will retain the secondary catalytic converters or in a racing application with our Secondary high flow Pipes. These downpipes will add a deep exhaust tone at lower RPMs and a nice sound improvement under wide open throttle. Weight savings is another great benefit from this upgrade with the Boost Logic pipes fabricated from high great lightweight stainless steel. (Note : Off road or race use only)
