N55 Downpipe V2 MAD BMW M135 M235 M2 335 435 4.0"

Upgrade to the MAD BMW N55 Catless downpipe to eliminate the backpressure caused by your stock catalytic converters. By upgrading to our downpipe, your turbo can now spool faster and achieve maximum power. As a bonus, your car will sound a lot nicer as well.

Expect up to a 30HP increase on a tuned BMW N55 with stock turbo, even more on cars with upgraded turbo.
