Title

3.0" Catless Downpipe For 2012-2018 BMW M5 M6 Gran Coupe 4.4T S63B44Tü V8 By Suncent®

Advantages of a catless downpipe
All-New Acceleration Experience
A cat-deleted exhaust system can simultaneously boost torque and reduce weight, delivering a significant acceleration improvement—shortening the 0-60 mph acceleration time by approximately 0.3-0.4 seconds.
Faster Turbo and Throttle Response
By removing the catalytic converter, exhaust backpressure is dramatically reduced and hot gases no longer accumulate in the turbo housing. This lowers the turbocharger’s operating temperature, cutting turbo lag and throttle response time by approximately 10–15%.
Improved Fuel Economy
By reducing exhaust backpressure, more air enters the combustion chamber, significantly enhancing fuel combustion efficiency and increasing fuel mileage by up to 5%. Whether for daily driving or track competition, it delivers more economical performance.
Deep, Resonant Exhaust Note
At idle and low RPM, the mid-to-low frequency rumble becomes richer and more robust. A light tap of the throttle unleashes a powerful turbo whistle and sharp exhaust bursts.
Reduced Failure Rate
The catalytic converter is a wear-prone component. By removing it, the exhaust system is simplified, effectively lowering the likelihood of failures.

Why remove the catalytic converter?
After removing the catalytic converter, exhaust gases can be discharged from the turbo more freely, effectively reducing heat buildup and lowering the turbo's operating temperature. At the same time, exhaust backpressure is significantly reduced, markedly improving engine intake efficiency—while gaining more torque and horsepower, fuel combustion becomes more complete. This allows you to fully unleash the passion of ultimate performance on the track, while also saving considerable fuel costs.
