Sport Cat-Back Exhaust System

The Eisenmann Sport exhaust system is a premium, German-made performance upgrade for the E46 M3, meticulously crafted from T304/T306 stainless steel. The exhaust features four 76mm round, straight-cut polished stainless steel tips, designed to fill the rear valence opening more substantially than stock. Eisenmann's philosophy centers on achieving the ideal exhaust note—a refined, muted rumble that enhances the vehicle's character without excessive volume, resonating with the expertise of an OE supplier to brands like Porsche and Mercedes AMG. Each system can be further tuned with optional center pipes, offering either a free-flow resonator for a more composed sound or a straight pipe for increased volume. As an OE supplier to several German marques, Eisenmann adheres to strict quality standards, with all Sport systems carrying German TUV approval. The company manufactures its exhaust components in-house, reflecting a commitment to old-world craftsmanship. A two-year warranty is included. Installation of this exhaust system is intended to alter the tone and increase the volume of the exhaust. It is the vehicle owner's responsibility to ensure compliance with all federal, state, county, or local sound regulations, as some jurisdictions have strict rules prohibiting factory exhaust modifications. Due to small production runs, availability can vary, and lead times have historically been up to 10 weeks when sold out. Contact the sales team for the latest estimated delivery times.
