The most straight exhaust system for 335d ever made!
Most important in one good exhaust is 2 things
1. Pefrect matching on the separate elbows and pipes without edges
2. To be straight as possible That means to be reduced all angles on the exhaust as possible. On the 5ft photo It can bee seen two downpipes, you can see the angle difference (2 x 80° vs 2 x 25°) The less angle exhaust allows much better exhaust gasses flow. Our tests shows reduce the EGT values and HP increase, especially on a high tuned vehicles.
Straight-through design enabled to improve horsepower and overall performance
Increases Horsepower up to 30+ BHP, dependant upon engine mods
