Enhance your BMW's exhaust system with the all-new Magnaflow Universal Muffler, available at an exceptionally affordable price point. Say goodbye to noisy and inefficient mufflers with this high-performance solution.

The Race Series muffler is meticulously designed for uncompromising performance, delivering an aggressive racecar-inspired sound. Its genuine straight-through design ensures the utmost high RPM power, while the 2.5" or 3" perforated core effectively eliminates backpressure, optimizing exhaust flow.

This muffler stands as the ideal choice for dedicated racers, turbocharged engines, nitrous oxide fuel systems, or vehicles equipped with wild cam applications. It boasts a 2.25" inlet, a 24" overall length, and a 4" diameter round, angle-cut tip.

Kindly note that this muffler is of universal fit for rear exhaust and may necessitate welding or fabrication for installation, as it is not a direct bolt-on component for any specific vehicle.

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!

This is the original Supersprint street rear muffler for the E46 M3. It's a direct replacement for the stock rear muffler but with less restriction and better flow. This exhaust is not overly loud (conforming to European noise restrictions) and no drone but is larger and heavier than the other Supersprint mufflers. It makes a deeper tone than with slightly more rasp than the stock system.

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.
