CTS Turbo RACE DOWNPIPE SET for BMW F85 X5M & BMW F86 X6M (2014-2019) 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. These race pipes are manufactured from high quality 304 grade stainless steel; hand TIG welded and back-purged to ensure years of reliable performance.

In addition to unleashing the power and performance of your S63 4.4L 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.

It’s time to fully unleash the performance of your high-performance SUV! Order your CTS Turbo downpipes + bootmod3 tuning; and leave the competition in the dust.

To remove the CEL that will occur, proper stage 2 tuning software must be used. Race/competition/testing use only!
