BimmerWorld Stage III Power Kit - E9X M3 S65

Intake, exhaust, and software bundle for 2008-2013 E9X M3.

Our Stage III package for the 2008-2013 E90/E92 M3 is a 3-part upgrade: intake, cat-back exhaust, and software. We don't touch the center section and catalytic converters. While a lot of power can be gained by removing the catalytic converters, this is not always desired or possible for some customers. Our Stage III gets the most from bolt-on modifications without hassle and side effects of cat-delete.

Macht Schnell M3 Intake
This kit consists of the Macht Schnell E9X M3 Stage 2 Intake Charge Kit.  It's our favorite choice for E9X M cars because it's designed for power! By replacing the restrictive stock filter with a larger, more free-flowing performance filter, the engine is able to breathe more air - and that means more power.

Magnaflow M3 Cat-Back Exhaust
Our package includes a MagnaFlow cat-back exhaust that produces a subtle throaty sound that enhances the V8 exhaust note without getting in the way. It's a fully stainless performance exhaust with dyno-developed power gains and an engineered system that minimizes drone. We wanted you to have all of the power but without the drama. Default system is for E92 M3 coupe - contact us for E90 M3 sedan system. This system is built to order. Typically lead times are about 30 days from order date.

Epic Motorsports Stage 1 street software
The software is Epic's Stage 1 custom ECU tuning. Epic tunes are able to provide more usable horsepower and torque outputs by modifying BMW’s dual variable cam timing (VANOS), drive by wire tables, and fuel and ignition maps. Better part-throttle drivability is also obtained. The vehicle’s top speed governor is removed. Custom software modifications for headers or other modifications are available. Rear O2 sensors monitoring, as well as other emission related items, can be disabled upon request for race cars and/or off-road use only vehicles. This tune includes the Engine Calibration Interface (ECI) with purchase.
