Supersprint BMW E46 M3 Stainless Quad Sonic Rear Exhaust - 4x80mm

046846

Supersprint is well known within the BMW E46 M3 community for producing some of the finest sounding and highest quality exhaust systems available. While many manufacturers focus development primarily on newer platforms, Supersprint revisited one of BMW M's most iconic models to engineer an all-new performance exhaust system for the E46 M3.

The Stainless Quad Sonic Exhaust features a unique four-chamber muffler design paired with a large single 3-inch inlet connection. This configuration is designed to support strong exhaust flow while delivering an aggressive and distinctive exhaust note from the naturally aspirated S54 engine, while saving over 33 lbs from the factory components.

Designed to be the lightest system they produce for the E46 M3, Supersprint's Quad Sonic Sound Package saves 7lbs over their Lightweight Race System.

Installation requires the Supersprint Section 2 Mid-Pipe, SKU 046803 (sold separately), which is specifically designed to connect to the Quad Sonic Exhaust's 3-inch inlet. The system is completed with four 80mm high-polished exhaust tips, giving the rear of the E46 M3 a more purposeful appearance to match the sound.

Manufactured in Italy from T304 stainless steel, the Quad Sonic Exhaust reflects Supersprint's long-standing focus on precise fitment, durable construction, and complete system development. Rather than treating the rear exhaust as an isolated component, Supersprint engineers each system to work as part of a complete exhaust package with an emphasis on sound, flow, and performance.
