Supersprint E46 M3 Performance Exhaust Systems and Sections

Supersprint E46 M3 exhaust sections can be bought separately or combined together as a reduced price package!

Supersprint's E46 M3 exhaust system components have been researched, designed and tested to insure additional power and to enhance overall performance. Each component from header to tailpipe is accurately tuned and suited to each particular engine by Supersprint engineers. Exhaust flow rates and velocity are dramatically increased by Supersprint designs while still retaining factory OEM diameter tubes. We know it is actually easier to lose horsepower through misuse of larger diameter tubing and badly designed silencers. All design is validated by extensive testing which includes hours of dyno testing on Supersprint's chassis dynamometer for optimal performance over the stock exhaust system. When you look at a Supersprint product you can see the attention to detail, the quality materials, precise welds, rather than crimped seams, and the superb finish. It's obvious Supersprint produces one of the best exhaust system in the world.

A critical balance between lower back pressure level and flow rate must be ensured for optimum performance. When Supersprint develops a system for a new car, hand built prototypes are made and extensively dyno tested, rebuilt and re-tested. Combinations of tubes and perforated cores with outside diameter ranging from 32mm up to 76mm are utilized for best results. Flanges and hangers are OE or better quality for a perfect fit every time. Housings are all manufactured from 1.5mm material that is MIG welded at all seams and these systems are 100% 304 stainless for durability.

The quality of a Supersprint system also includes meeting sound emissions restrictions. All Supersprint street legal systems meet the stringent requirements of TUV testing for quality, design, construction and sound emissions.  All components are 100% stainless steel, and all tubing is mandrel bent to assure you the highest flow volume. Applications include all E46 M3 models.

Options Include:

Section 1:

• Straight Pipe - This section has no catalysts or resonators for 100% full flow and sound.
• Straight Pipe Including Catalyst - This section incorporates high-flow catalysts to comply with emissions regulations. The reduced cell count from the OE 400 CPSI to a high flow 200 CPSI makes the Supersprint racing converters the most free flowing on the market today.
• Supersprint Section 1 can be used with factory exhaust manifold and/or Section 2.

Section 2:

• X-Pipe - This section has no resonators for 100% full flow and sound. An X-pipe is incorporated into the section for added savaging and flow.
• X-Pipe Including Resonator - This section has a tuned resonator to reduce overall sound volume. An X-pipe is incorporated into the section for added savaging and flow.
• Supersprint Section 2 can be used with factory Section 1 and/or Section 2.

Section 3 with Connecting Pipes:

• Street Muffler - This muffler offers a mellow, drone free sound designed specifically for street use.
• Sport Muffler - This muffler set is designed for a sportier tone and reduced weight.
• Race Muffler - Offers the most sound and lightest weight. Can be used in conjunction with the resonated Section 2 for an aggressive street system.
• Each version has 80mm polished stainless steel tips.
• All versions include the necessary connecting pipes for mounting to factory Section 2 if applicable.
