Supersprint Headers for BMW | E46 | 325i | 325ci | 330i | 330ci (LHD)

Supersprint manifold for BMW M54 engine.

 

For models fitted with pre-catalytic converters this component will replace them (pre-cats delete).

The secondary O2 sensors issue must be addressed with sensor cheaters (also known as microcats or emulators), ECU tune or fitting the Supersprint front pipes with metallic cats and extending the sensor wires plugging the sensor after them.

 

A good header design is key to unlocking performance gains from naturally aspirated motors. At Supersprint every header is designed, developed and manufactured within our factory here in Mantova, Italy.

 

With performance gains the main objective, we study and design primary and secondary piping configurations with varying diameters and lengths. These are then tested on our in-house MAHA Dynamometer enabling us to recognise the optimum setup. We also ensure the 02 sensor bungs remain in their original position for ideal fitting.

 

Supersprint headers are manufactured using industry leading techniques from the best German 304 and 310S stainless steel with piping thickness variable from 1 to 1.5mm, along with CNC machined, hi-precision laser cut flanges built from 409 and 304 steel for perfect fitment and longevity. Our joints are TIG welded in order to guarantee strength and durability. For temperature critical, delicate applications we also use Inconel for some of our products. 

 

These materials and processes ensure Supersprint headers are extremely high quality, durable products that offer true, tangible performance gains.

 

Supersprint inc. was formed in 1955 with the objective of designing and building the highest quality exhaust systems in the world. Each Supersprint exhaust system is hand crafted from the finest Italian sourced materials; 304SS, 310SS and Inconel.

 

Italian made and assembled; all Supersprint exhaust components are hand made in Supersprint's Mantova factory. The sole components outsourced are the catalytic converters made in Germany by HJS; the world's leading catalytic converter manufacturer.

 

Supersprint is the industry's leading research and development company, they offer the widest variety of performance headers in the world with many patented innovations such as stepped design primaries, spring-loaded floating merge collectors and more.
