CTS Turbo RACE DOWNPIPE SET for BMW F85 X5M & BMW F86 X6M (2014-2019) equipped with the powerful S63 engines 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.
