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 so this kit is fully emissions legal in 49 states. 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 E9X M3 Intake


E9X M3 MS Intake
Macht Schnell E9X M3 Stage 2 Intake Charge Kit. It's our favorite choice for E9X M3 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. The disruptive accordion-style stock intake elbow that connects the air box to the intake manifold is also replaced. This Macht Schnell replacement Intake Charge Pipe (ICP) has very smooth and glossy interior walls, and it's also 18% larger by volume, so you get considerably more air while eliminating the turbulence and resistance that the stock elbow produces. The ICP is constructed from super-strong polyethylene and has a textured exterior that perfectly matches the texture of the OEM intake manifold for a stock look. Macht Schnell's own Intake Charge Scoops are part of this cost-effective kit, and they help to create a matched combination that provides maximum air delivery to your S65 engine for noticeable power gains.


Magnaflow E9X M3 Cat-Back Exhaust


E9X M3 Mufflers

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.

MagnaFlow M3 Exhaust Features:
  • 3.5" polished double-wall tips
  • dyno-developed
  • superior fit and finish
  • power but civilized sound
  • weight savings over stock
  • lifetime warranty
  • Made in the USA
Default system is E92 M3 coupe. E90 sedan systems also available.


Epic Motorsports Software Tune


E9X M3 Epic Tune
The software in our package consists of Epic's 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. This software has been specifically calibrated for the modifications in our Stage III kit so you can get the most from your upgrades. Epic tuning also improves part-throttle drivability and smoothness. The vehicle’s top speed governor is removed. Other custom tuning is also available. This tune includes the Engine Calibration Interface (ECI) with purchase.
