Cts Turbo BMW F90 M5/M5C & BMW G15/G16 M8/M8C Race Downpipe Set

CTS Turbo CTS Turbo BMW F90 M5/M5C & BMW G15/G16 M8/M8C RACE DOWNPIPES 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 parts. 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 race downpipe 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.
