One of the first things we noticed when we got our E90 M3 back in 2008 was the exhaust restriction caused by the placement of the front cats. For space considerations, the factory exhaust setup is crimped in an odd way and the cats are a high cell count. Both combine to rob horsepower. It seemed logical to us that replacing the first set of cats with a set of straight pipes would really open up the breathing and make serious horsepower. Our M3 Test Pipes were designed specifically for race/track use and offer a cost-effective means of removing the very restrictive primary cats. On our Turner M3 and BMW Motorsport M3 GT4 racecars the primary cats and restrictive piping is eliminated. Our M3 cat delete pipes were the first on the market and have proven again and again to make big power on their own or especially when paired with our Stage 2 performance software. (click here)

Our Test Pipes are Made in the USA with strict production tolerances and quality control. We manufacture our pipes with high quality, mandrel-bent stainless steel pipes and laser-cut flanges for an optimum fitment. New gaskets are included. For installation, simply measure and cut the stock front pipes and the Turner Test Pipes slide on. The factory secondary cats remain in place. Your original O2 sensors plug into the Turner Test Pipes. There isn't a better 'bang-for-your-buck' upgrade on your M3 than a set of our Test Pipes.

This part alters or deletes the emissions equipment on your car, and may not meet emissions standards in all states. Because of this, we require a waiver of emissions compliance to be signed and sent in to TMS. You can download the waiver here.

The oxygen sensor is vital to the performance and drivability of your car. The engine computer relies on data from the sensor to make adjustments in engine efficiency and performance. When your BMW oxygen sensor fails, the computer can no longer sense the air/fuel ratio, so it ends up guessing -- resulting in poor performance, poor gas mileage, and increased pollution. Make sure your BMW engine performs as it should, and doesn't use more fuel than it needs to, by simply changing your oxygen sensor today. There is no lifespan on O2 sensors but there are several fault codes that indicate a failed sensor (O2 monitoring, cat efficiency, O2 heating circuit, O2 readiness, and others). The O2 sensor is heated and has a self-calibration feature so once you get the codes or feel performance has suffered, a new sensor is a good starting point to get you back to peak performance. Bosch's Oxygen sensors are high quality and will give you the the longest and best performance for the price.

This is the pre-cat oxygen sensor. This is a OEM replacement part for BMW part # 11787558073 and .

Bosch Motorsport LSU 4.9 Wideband Lambda Sensor

T#:180872
Part#: 0258017032
Ships in 2 Days
$158.84

This Bosch Lambda sensor is used with aftermarket engine management systems around the world. It's a universal racing oxygen sensor but only works with specialized racing engine management, advanced air/fuel and Lambda gauges, and Bosch Motorsport ECUs and Lambda control boxes (LT4). This is not a universal sensor to work in any production BMW. This is a motorsport-only wideband O2 sensor.

This sensor is designed to measure the oxygen content and Lambda value of exhaust gases in automotive gasoline engines. The wideband Lambda sensor LSU 4.9 is a planar ZrO2 dual cell limiting current sensor with integrated heater. Its monotonic output signal in the range of λ = 0.65 to air makes the LSU capable of being used as a universal sensor for λ = 1 measurement as well as for other Lambda ranges. The connector module contains a trimming resistor, which defines the characteristic of the sensor. The LSU4.9 operates only in combination with a special LSU-IC, used in most Bosch Motorsport ECUs and Lambda control boxes (LT4).

The main benefit of the LSU is the robust design combined with the high Bosch production quality standard.

Application Hints:

  • The Lambda sensor should be installed at a point which permits the measurement of a representative exhaust-gas mixture, which does not exceed the maximum permissible temperature.
  • As far as possible install the sensor vertically (cable upwards).
  • The sensor is not to be fitted near to the exhaust pipe outlet, so that the influence of the outside air can be ruled out.
  • The exhaust piping must be free of leaks in order to avoid the effects of leak-air.
  • Protect the sensor against condensation water.
  • The sensor is not to be coated or painted, nor is wax to be applied or any other forms of treatment.
  • Use only the recommended grease for lubricating the thread.

Application Data:

  • Exhaust Gas Pressure< 4bar
  • Exhaust Gas Temp Range (operating)< 930*C / 1,706*F
  • Exhaust Gas Temp Range (max)< 1,030*C / 1,886*F
  • Hexagon Temp< 600*C / 1,112*F
  • Cable and Protective Sleeve Temp< 250*C / 482*F
  • Connector Temp< 140*C / 284*F
  • Max Vibration (Stochastic Peak Level)< 1,000 m/s2

Mechanical Data:

  • Weight (without cable)120g
  • Length (without cable)84mm
  • Cable Length32.2cm
  • ThreadM18x1.5
  • Wrench Size22mm
  • Tightening Torque40...60Nm

Price is per sensor.

Turner Corsa Performance T-304 stainless exhaust system for 2008, 2009 and newer E90/E92/E93 M3 (sedan, coupe & convertible). Features mandrel-bent tubing, polished quad 3" tips (double-walled, angle cut and staggered), and drone-free quiet-cruising, thanks to patented Reflective Sound-Cancellation (RSC) technology. This is a drone-free exhaust system, delivering a pleasant sound at idle and cruise and a muscular roar at high rpm.

How is this accomplished? The RSC technology is a non-electrical noise control system without the complication of incorporating the use of electronics or speakers. Essentially, engine sound (pressure) waves are reflected in passages inside the muffler 180 degrees out of phase to cancel out unwanted sound waves. The result is a "tuned" muffler that "cleans up" the noise without eliminating the pure sound of power associated with a high-performance vehicle. Using the Corsa technology, the stainless steel mufflers are tuned to eliminate passenger cabin resonance and produce just the "right" sound. The result is quieter cruising with an awe-inspiring roar at full throttle. This system is amazingly quiet during normal cruising, due to the "no drone" RSC technology, yet still has an aggressive presence and full sound while under throttle. This gives your E90/E92 M3 an ideal sound for those that want an aggressive "roar" while driving hard, yet still want a more discrete lower volume for normal cruising. (Please check out the video below for a sound sample on a 2008 M3 coupe).

As well as the tuned sound and drone eliminating sound, the mufflers on this E90/E92 M3 system use a straight-thru flow design for maximum flow and the least amount of restriction. Decreasing the restrictive back-pressure results in more horse power and torque, as well as the inspired sound this system creates for your M3's 4.0 liter V8 engine. There is no effect whatsoever on emissions, as this system does not replace or inhibit the your M3's factory catalytic converters, so there will not be any "Check Engine" warning lights. Emissions-legal in all 50 states. Made 100% in the USA, this exhaust features a lifetime warranty from the manufacturer. Includes full installation instructions, with detailed photos for easy and straight forward installation.

aFe Mach Force Race Center Pipe with Cats - E9X M3
AFE - Corporate Logo
T#:180852
Part#: 49-36316
Direct Ship
$1,562.74
$1,562.74

The aFe Race Center Pipe eliminates the factory primary and secondary catalytic converters in favor of 2.5" mandrel-bent stainless exhaust with 200-cell race cats. This aFe exhaust section fills the need for a E9X M3 center section with better flow than stock but that still incorporates catalytic converters. aFe recorded gains of 21whp and 35ft-lbs of torque on their dyno (when also combined with the aFe intake and mufflers).

aFe spent considerable time developing a system to eliminate both sets of stock cats and the center resonator for maximum flow but also doesn't lose torque or power at any RPM point, while also bolting to the factory headers and rear mufflers. It's a direct replacement for the stock section 1 and section 2 mid-pipes and includes a tuned center x-pipe to evenly balance exhaust pulses and maintain backpressure through the system. It uses all of the factory mounting locations, gaskets, and hangers and is made from the best 304 stainless steel.

By tuning the exhaust with different pipe diameters and the location of the x-pipe crossover, the aFe Race Pipe produces a very aggressive, raucous, and powerful exhaust note even when used with the stock muffler system. By opening up the exhaust and deleting the two restrictive cat sections and resonators, you will be able to hear a lot more of the exhaust as well as a deeper tone with more rumble - and with a big bump in power to go along with the sound! Don't be misled by other "race" pipes with minor sound changes - the aFe exhaust sounds a lot like our own E92 M3 racecars.

As used on the Lime Rock M3 Project Car
With the racetrack and the street in mind, this new exhaust system is crafted from an extremely heat-resistant and lightweight chrome-nickel alloy called Inconel®. This flow optimized exhaust system reduces exhaust backpressure and allows the M3’s 414 horsepower S65 V8 engine to produce an even more powerful sound. Inconel’s unique qualities allowed engineers to reduce the thickness of the tubing from 1.5mm to 0.8mm. This resulted in a weight reduction of approximately 40%, or about 20 lbs. when compared to the stock exhaust system. Inconel has also proven to be very corrosion resistant and has been used at the highest level of Motorsports. The M Performance Exhaust includes perforated inner pipes and polished titanium tips, which are laser engraved with the M logo. It represents the ultimate in technology and sportiness, accentuating the individual character of the BMW M3. The exhaust was developed using state-of-the art CAD and FEM technology ensuring optimum fit and OEM quality.
