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)
