This is the special Downpipe-Back version of the BMW E90/E92 335i CNS Racing Power Exhaust System. This includes a complete dual muffler, plug and play mandrel bent stainless steel piping and an X-pipe.

A vehicle's exhaust system is one of the most important factors in engine performance. The pipe size and flow rate have a direct effect on horsepower potential. With a non-sufficient exhaust flow, your engine's full potential will not be realized.

The exhaust system finalizes and determines the full potential of a modified engine. A high-performance exhaust system will allow additional engine modifications to come alive.

CNS Racing has been working closely with BMW 335i enthusiasts to configure the optimum exhaust product for both the street and the race track. The CNS Racing Power exhaust system is hand crafted with a sound absorbing design for maximum horsepower as our top priority.

- The CNS Racing Power exhaust system has been tested to be the best sounding exhaust for the BMW 335i. Attention and compliments are guaranteed! It is described as an exotic V6 twin turbo performance sound.

- The sound levels are perfectly balanced inside the cabin and out. Perfect for street driving even with small children.

- There is no drone or rasp at any RPM levels unlike most 335i exhausts on the market.

- Monster 3.5 or 4.0 inch / 89 or 102 mm exhaust tips! The largest tips that can fit in the OEM bumper.

- The system is made of high quality larger 2.5 inch 304 stainless steel unlike the low cost competitor exhaust.

- Easy installation can be performed by any exhaust shop.

- This package removes the OEM resonator and the second pair of catalytics to increase flow and performance. (We also offer a CAT-back system that retains the 4 catalytics for emission reasons)

- Two mufflers are included with hangers and tips. Most competitors only have one muffler which decreases flow and performance.

- 35+lbs savings over stock and excellent HP gains!

- One high flow X-pipe.
