Eisenmann GT4 Edition race exhaust for F80 M3/F82 M4 is the ultimate expression of race-inspired sound and light weight. The true purpose of this system is to lose weight and the Eisenmann GT4 exhaust mimics the factory Motorsport GT4 exhaust very closely by deleting the mufflers altogether. This rear exhaust section weighs only 28.6lbs! This muffler-delete design on the M3/M4 is not for the shy and reserved types - this exhaust will wake the neighbors and turn heads. Although technically street-legal and does not affect emissions at all, we expect this exhaust will not be used on long highway drives where drone at certain RPM may interfere with comfort.

The M3/M4 GT4 Eisenmann exhaust is a true polished stainless axle-back system that clamps to your stock center section. The tips are 90mm round straight-cut stainless steel - larger than stock and look seriously impressive in the rear valence.

This axle-back system can be matched with a center pipe to further tune the sound - a free-flow resonator to cut drone or straight pipe for even greater volume.

Eisenmann is based in Hemmingen, near Stuttgart, and manufacturers all of their exhaust components in-house. All Sport systems carry German TUV approval and Eisenmann is an OE supplier to Porsche and Mercedes AMG, which means the factory must meet ISO standards. With close relationships and respect among German manufacturers, Eisenmann is often first to market with performance exhaust systems and always produced with outstanding quality. A two year warranty is included.

A version of this exhaust is also available with high-flow racing catalytic converters.
