Free ground shipping! Fan of the rasp that comes from the S54 engine? This front exhaust section replaces the single resonator in the US exhaust (or the cats in Euro models) with a straight-through pipe. This can be a direct bolt-on to the stock or Euro headers and includes rear O2 sensor ports (for Euro models, must be plugged for US models). You can use this with the Supersprint resonator delete section 2 pipe for the max rasp effect. Or mount it with any other section 2 exhaust to fine-tune your sound. 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 preference. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. 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 part alters or deletes the emissions equipment on your car. Because of this, we require a waiver of emissions compliance to be signed and sent in to Turner Motorsport.

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).

The Race Series muffler is meticulously designed for uncompromising performance, delivering an aggressive racecar-inspired sound.

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.

BMW's original muffler hanger (part number 18201401797) works great at first but tends to fail over time, leading to sloppy exhaust movement and excessive noise. This failure is due to both heat and the heavy exhaust wearing down the hanger until it eventually tears, allowing the exhaust to shift around freely, banging off of nearby components. In order to address this common problem, Powerflex developed their own polyurethane rear muffler hanger that features a heavy-duty, yet lightweight, machined aluminum bracket. Polyurethane is significantly more resistant to the effects of heat and weight over time compared to rubber, meaning you can expect this exhaust hanger to last many times longer than your stock BMW hanger.

When building your vehicle for the track, there are a lot of considerations to take into account. One major factor is your exhaust system. Many exhaust systems are only designed for so much exhaust flow, which can really limit the total amount of potential power your engine can produce. To address this issue with heavily tuned, turbocharged, or supercharged E46 M3s, Supersprint now offers a new line of high performance Center Twin-Pipe Exhaust Pipes that are designed to provide you with a significantly higher exhaust flow than their original performance exhaust pipes, 787503 (Resonated) and 787513 (Non-Resonated), designed for street and light track performance.

This twin pipe system utilizes two high flow pipes instead of a single large pipe, allowing for up to 25% greater total exhaust flow. Thanks to the increased total flow, these center pipes are capable of supporting S54 engines producing over 400whp, perfect for all highly modified street cars or performance track vehicles.

This specific option offer's pipes that are resonated to prevent excessive noise and drone that may be experienced at cruising RPM speeds.

Fits the following Vehicles:
2001-2006 E46 BMW M3
