CTS Turbo Crossover Exhaust Pipe for G80/G82 BMW M3/M4

On the G80 M3 and G82 M4, the left downpipe feeds a crossover pipe that runs under the transmission. BMW squashed that pipe into an oval to clear the gearbox, which creates turbulence and slows exhaust flow. CTS Turbo's replacement keeps a round section the whole way.

What you get

• Round 3" (76 mm) tubing in place of the oval factory section.
• 304 stainless steel construction.
• Laser-cut flanges.
• Designed from 3D scans, with flow routing checked in CAD simulation.
• Fits both left- and right-hand-drive cars.
