Supersprint E9X M3 Performance Exhaust Systems and Sections

Supersprint E9X exhaust sections can be bought separately or combined together as a reduced price package!

Supersprint's E9X 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 constructed of 100% 304 stainless steel.

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. Supersprint recommends the use of complete systems (header, center & rear muffler) to achieve the highest performance gains. All components are 100% stainless steel, and all tubing is mandrel bent to assure you the highest flow volume. Applications include all E90, E92, and E93 M3s.

Options Include:

Section 1:

• Straight Pipe - This section has no catalysts or resonators for 100% full flow and sound.
• Straight Pipe Incl. 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.
• Each version must be used with a Supersprint Section 2 X-Pipe (below).

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 Incl. 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.
• Each version must be used with a Supersprint Section 1 Straight Pipe (above).

Section 3 with Connecting Pipes:

• Street Muffler - This muffler offers a mellow, drone free sound designed specifically for street use.
• Sports Mufflers - This muffler set is designed for a sportier tone and reduced weight. This sport muffler set can be paired with the resonated X-Pipe for a great street/track setup!
• The Street and Sport Mufflers have 80mm polished stainless steel tips.
• Both versions include the necessary connecting pipes for mounting to factory Section 2 when applicable.
