Product Description
We are proud to introduce our TM Performance 3'' G82 M4 Downpipes for the S58 engine. These 3'' downpipes are the best choice for your car. By reducing the restrictive catalytic converters in the OEM downpipes, back pressure is reduced greatly. Which results in faster spool, and also an increase in power & a more aggressive exhaust sound.
Rather than necking down close to the turbos like most of other brands in the market, our G82 M4 downpipes features a full 3'' design up to the last couple of inches of the pipe. This design could make an increase of flow, leading to the gain of horsepower.
FEATURES:
100% made by SUS304, using mandrel bends
Homogeneous TIG welded joints
Factory O2 locations retained
Major increases in power
Improved turbo and throttle response
Elimination of turbo lag
Exotic exhaust sound
Lighter weight than the stock system
Quicker turbo spool
