The crowning touch to an exotic and wicked sounding E46 M3! The Supersprint Race mufflers are very popular for the shriek they add to the S54's exhaust note. A full Supersprint system with these mufflers is one of the sexiest E46 M3 exhaust sounds we've come across - especially in a tunnel! The Lightweight Race mufflers are the capstone to that system. You can use them with any other center section or with the Supersprint section 2 (with or without a resonator).

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preferance. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

The Dinan sport muffler is designed to compliment the E46 M3 and not overpower the driver and passengers with harsh tones. Dinan engineers their exhausts to sound great and be a natural fit to the character of the car as well as produce more power and torque. Dual 3.5" stainless satin black tips engraved with the Dinan logo fill out the rear valence. Annoying highway drone has also been engineered out of the system. Dinan uses only 304 stainless steel in their systems for the maximum corrosion protection. This system replaces the factory rear mufflers at a pre-determined cut point on the stock exhaust, which makes for an easy installation and you can reinstall your original mufflers using factory hardware. Detailed installation instructions are included.

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere. The Dinan sport muffler is worth 3 point towards your Dinan badge.

Please note: only the passenger-side tips are functional (exhaust exits from the two right side tips only). The driver's side tips are only for aesthetics. Dinan has engineered it this way to minimize drone.

Supersprint revised their rear muffler designs to offer this 'Generation 2' version - smaller body and freer flow than the standard Supersprint muffler but quieter and more civilized than the full Lightweight Racing mufflers. It's still lighter than the stock original or standard Supersprint mufflers. The sound is a more refined version of the full racing mufflers with less drone and quieter overall but still with plenty of ripping S54 aural tone.
