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:

These Supersprint section 1 straight pipes are designed to follow the larger pipe sizing of the Supersprint stepped headers. With straight pipes and headers, there will be no cats in the system, making this perfect for race or track-only cars. The straight design will be louder and let more of the S54 rasp to come through. With headers and the Supersprint race mufflers the sound is simply intoxicating. You can use this section with any other section 2 pipe and muffler.

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!

Experience the latest design innovation from Supersprint for the E46 M3 -- 'stepped' design headers. While the technology has been in widespread use in Formula 1 for awhile, this is the first application of a stepped design on the E46 M3. In an engine that is tuned as much as the S54, airflow management is critical in getting big horsepower numbers from the exhaust. The Supersprint design is the next step in innovation in header design. By slightly increasing the size of the pipe diameters as the exhaust system moves away from the engine, the exhaust can flow more air. Supersprint's design is tuned specifically for the S54 engine which is important in making more power without losing low-end torque. The headers merge into a precision-fit merge collector. After the headers, the stepped piping size continues into the Supersprint section 1 with or without cats. The section 1 must be purchased separately. Any section 2 and rear muffler can be used with the Supersprint section 1. Our most-popular package for track cars is for the stepped headers with no cats (straight pipe) but cats are available for people who want to keep emissions in check (or if your rules require them). Total horsepower gain with the complete system over a US M3 would be more than 30hp.

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 design because every aspect is done to such a high level. 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!

We also recommend using this system on the M3 with special software. The Shark Injector software has been specifically designed for cars running headers but no cats. The software "turns down" the readings from the rear O2 sensors and modifies the tolerances for the EGT sensor. Using an exhaust without the cats and proper software will surely cause a Check Engine Light. Click here for more info on the software.

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).

Want more rasp and volume to come through from your exhaust? This Supersprint section 2 will replace and delete the factory resonator that sits before the muffler. Without the resonator there to dampen the sound the overall volume will increase and let more S54 rasp come through. Combine this with the Supersprint section 1 straight pipes for even more Motorsport rasp. This section 2 pipe will bolt up to a stock section 1 or cat section and any muffler. It's perfect for getting just a little more volume from your stock exhaust without changing the muffler.

    Custom Performance Innovations has produced their own performance headers for the E46 M3 with outstanding quality, workmanship, and power gains. The CPI headers use a stepped design of increasing pipe diameters and mandrel-bent piping for superior exhaust flow. The header tubes are slightly over-sized from the stock exhaust ports and all connections have smooth transitions which promotes exhaust scavenging and flow. The craftsmanship is among the best in the M3 header market and unbeatable for the price. The headers are made with 321 stainless with a satin finish and O2 sensors and EGT sensor ports are included in the correct places (a common fitment issue on lesser-quality headers). To make your installation easier, pick up the Gasket and Hardware Kit from the options below.

    CPI measured gains of 15hp and 12 ft-lbs at the wheels using a Dyno Dynamics dynamometer (which displays a lower number compared to other brands of dynos).

    With the quality of the design and craftsmanship, this header is unbeatable for the price!

    Features:
  • T321 stainless steel with satin finish - better corrosion resistance than 304 stainless
  • TIG welded connections - stronger weld with less fatigue to surrounding metal
  • Stepped design with the leading pipes fitted inside the secondary pipes (instead of the opposite) - un-impeded flow
  • 3-way merge collector on both banks using same construction as above - improved exhaust scavenging and flow
  • Precision cut flanges and blended with the exhaust tubing - no lip, edge, or obstruction to flow
  • Outlet flanges that will work with nearly any Section 1 system - greater flexibility with the rest of your exhaust
  • Careful placement of O2 sensor and EGT sensor bungs - hassle-free fitment

    This Bosch Lambda sensor is used with aftermarket engine management systems around the world. It's a universal racing oxygen sensor but only works with specialized racing engine management, advanced air/fuel and Lambda gauges, and Bosch Motorsport ECUs and Lambda control boxes (LT4). This is not a universal sensor to work in any production BMW. This is a motorsport-only wideband O2 sensor.

    This sensor is designed to measure the oxygen content and Lambda value of exhaust gases in automotive gasoline engines. The wideband Lambda sensor LSU 4.9 is
