CTS Turbo BMW F90 M5/M5C & BMW F91/92/93/ M8 High-Flow Cats Downpipe Set

CTS Turbo F90 M5/M5C & F91/92/93/ M8 High-Flow Cats are made to maximize exhaust flow for highest power gains. Do not compromise performance and sound with factory parts.

Designed using the latest in CAD technology; this part is made to fit perfectly in place of restrictive factory catalytic converter. Manufactured from CAST T304 stainless steel; hand TIG welded and back-purged to ensure years of reliable performance.

In addition to unleashing the power and performance of your 4.4 Twin Turbo, our High-Flow Cats will make your vehicle sound like it really should. When installed with factory exhaust it produces a louder and deeper growl with much more pronounced exhaust “crackle” on downshift. While up-shifting you will enjoy a confident “punch!” as you bang through all 8 gears. The sound will be even louder if you already have an aftermarket exhaust system.
