MTC Motorsport Downpipes with 200 Cell Hi-Flow Sports Cats & Heat Shields – 540C
Upgrade the exhaust system on your McLaren 540C with MTC Motorsport’s high-performance downpipes featuring 200 cell high-flow sports catalytic converters and integrated heat shielding. Designed to reduce exhaust back pressure while retaining catalytic functionality, this setup improves turbo response, exhaust flow, and sound without the harshness of a full decat system.
Engineered as a direct replacement for the factory downpipes, these units offer an ideal balance between performance, sound enhancement, and usability for fast road and track-focused builds.
