Supersprint Turbo Downpipe BMW E92 335i Coupe 07-11

Supersprint Turbo Downpipe BMW E92 335i Coupe 07+

The turbo down pipe is manufactured from 304 stainless steel using all mandrel bent tubing and each pipe is 65mm in diameter resulting in ultra low backpressure, assuring instant turbo spool up for maximum torques and horsepower gains. The results of installing a complete turbo to tail pipe Supersprint system are a phenomenal 26 hp with a torque gain over 20 lb/ft. The stock down pipes cause a major restriction in the exhaust flow. BMWs solution to deal with the limited space in the engine compartment is to crush the turbo outlet tubes to reduce the size of the tubing. Doing this created undesirable backpressure. For emission purposes the factory also incorporated built-in pre-cats directly after the turbo outlet ports. This make the exhaust gas backpressure rise to extremely high levels at all rpm and engine loads. This design retains excessive heat in the engine and affects performance in a negative way. On the contrary, the design of the Supersprint down pipes takes advantage of even the smallest space available and frees the exhaust gas flow dramatically. The SS pipe cross section (no crushed pipe) remains constant all along the down pipes and the pre-cats are totally eliminated.
