Supersprint BMW Exhaust - E30 318, 325, and M3, 1984-1992

Dyno-testing
All design is validated by extensive testing which includes hours of dyno testing on Supersprint's exclusive in-house Maha 4-wheel chassis dynamometer. In fact no other exhaust manufacturer, race team engine testing department or car manufacturer has the performance evaluating experience of Supersprint.

The Supersprint dyno performs over 1,000 test runs each year. The engineering staff at Supersprint are often called upon to provide closed-door dyno testing for the worlds top racing teams. Private teams and factory teams alike depend upon the extensive knowledge of Supersprint to prepare for world class, rally and road race events.

All this experience provides the Supersprint staff with a database of powerband information unequaled in the industry.

Product Development
Supersprint does it's homework on the dyno, the street and the track. Our extensive knowledge has been earned on thousands of cars around the world. This knowledge provides Supersprint with the uncanny ability to extract power from engines when other exhaust manufacturers can only produce higher noise levels. Supersprint products are developed around scientific knowledge not assumptions. Supersprint designs and builds based on each engine's performance characteristics. Because it is actually easier to loose horsepower through misuse of larger diameter tubing and badly designed silencers, exhaust flow rates and velocity are dramatically increased by Supersprint designs while still retaining factory OEM diameter tubes.

Quality and Longevity
To protect against corrosion each non-stainless system receives an aluminized coating inside and out. All internal tubing, resonators and tail pipes are stainless steel. Packing material is longstrand stainless steel wool and rockwool.

These materials are manufactured to Supersprint specs and provide much higher heat resistance than fiberglass. Stainless wool is packed around internal perforated tubing for sound control and rockwool surrounds the stainless wool to fully pack the interior chamber.

These materials insure a longer lasting system that will not blow out packing due to heat break-down, and zone that retains sound quality for many years.

Please check your individual vehicle laws to determine suitability for use on public highways. Some pieces designed for use in a Supersprint full system only, please call or email with questions.  Specific item descriptions:

• HEADERS - To be used as a replacement for the exhaust manifold, only in combination with a Supersprint resonator or catalytic converter
• RESONATOR - Replacement for the catalytic converter in E30 systems.  The addition of a resonator adds torque and reduces noise levels slightly.
• TEST PIPE - Replacement for the catalytic converter in E30 systems.  This pipe will give the best increase in Hp.
• RACE CAT - Replacement for the catalytic converter in E30 M3 systems.  For race use when a converter is required.
• MUFFLER - Can be added to a stock system or a full Supersprint exhaust for maximum performance.
