CTS Turbo BMW F10 M5/M5C & F06/F12/F13 M6/M6C High-Flow CATS are made to maximize exhaust flow for the highest power gains.

Designed using the latest in CAD technology; this part is made to fit perfectly in place of the 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 a 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.
