Boost Logic F90 M5 Catless Downpipes
These downpipes will remove the primary catalytic converters and have a smooth design to increase the flow of your exhaust system. These downpipes can be ran with stock secondary pipes which will retain the secondary catalytic converters or in a racing application with our Secondary Cat Deletes 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 : All of our catless products are designed and should be intended for race use only)
