Upgrade Your Engine with an Efficient O2 Sensor Replacement

If your engine is triggering an oxygen sensor check engine light, it's time to consider a replacement with this high-performance unit. The O2 sensor is a critical component that measures unburned fuel in the exhaust pipe, enabling precise fuel mapping adjustments for reduced emissions and improved fuel economy.

When the O2 sensor malfunctions, your vehicle's MPG and overall performance can suffer. The good news is that replacing this unit is a straightforward process that can quickly restore your engine's performance and mileage. To ensure easy removal in the future, apply some anti-seize on the threads.

Regular, scheduled maintenance should include the O2 sensor replacement, as these sensors have a tendency to degrade slowly over time.

The factory cast-iron exhaust manifolds originally fitted to M50, M50TU, and S50B30US-powered E36s are notorious performance bottlenecks, plagued by excessive weight and a tendency to crack over time. Our Equal Length "Shorty" Exhaust Headers offer the ultimate remedy. Engineered specifically to maximize exhaust flow and encourage exhaust gas scavenging, these headers unleash a noticeable boost in overall engine efficiency and grant your M5X that crisp, aggressive inline-six growl without sacrificing low-end torque.

Unlike restrictive, uneven OEM cast-iron manifolds, our design utilizes high-quality T304 stainless steel construction shaped by precision mandrel bending. This specialized process ensures a uniform pipe diameter throughout every bend to maximize exhaust gas velocity and eliminate internal turbulence. The flow-optimized, equal-length primary runners merge seamlessly into a heavy-duty cast stainless steel collector, creating a restriction-free transition that dramatically improves scavenging. Our refined design completely transforms your driving experience, delivering a deeper, more pronounced tone under load while remaining perfectly civilized and drone-free at cruising speeds.

Built to endure years of high-RPM track abuse and extreme thermal stress, these headers are engineered with longevity in mind. Every joint is meticulously TIG-welded for exceptional structural integrity, ensuring the tubes can handle intense heat cycling without cracking. To guarantee a permanent, leak-free seal, the headers feature thick, precision laser-cut flanges that aggressively resist warping over time. Best of all, this is a true, headache-free upgrade; they drop directly into the E36 chassis and mate perfectly with your factory mid-pipe using OEM gaskets and hardware, requiring absolutely no custom fabrication or modification.

This electric valve serves one of several purposes depending on which car it is used on. Please read the application listings below to ensure you are purchasing the correct part. 

Pierburg pumps are some of the most trusted and widely used on the market. From fuel, water, air and vacuum Pierburg has you covered with OE quality and reliable performance year after year.

Performance Axle-Back Exhaust - E36 M3:

Finally the answer to your E36 exhaust woes! Upgrade from your old, crusty or quiet exhaust that lacks the OOMPH you want to hear when stepping on the gas. Our crew at Turner have been describing this exhaust with words like “symphony” and “hearty” with its smooth and low frequency tone. This is the kind of exhaust we stand outside and listen to as our residential test vehicle rolls out from work heading off in the distance while singing the oh so sweet straight six sound.

Our new E36 cat-back is a tribute to the E36 M3 in more ways than one. The exhaust features 90s styling exhaust tips to compliment the sharp yet rudimentary body lines. Just like the E36 our exhaust was designed to be raw, straight to the point, lightweight and timeless.

To accomplish these goals our engineers revved up their creativity and went straight to work. Adapting straight to the mid-pipes our engineers transformed the lackluster 2.0” tubing and stepped up to a true-dual 2.5” exhaust with an integrated x-pipe to smooth out the flow and fine tune the exhaust note just how we wanted. Towards the rear of the vehicle you will find a light-weight and perfectly spec’d muffler featuring fabricated sheet metal hangers, slash cut integrated tips and achieves a fine-tuned exhaust note.

We can only hope the community enjoys this exhaust as much as we at Turner enjoy it. As a part of the community, we are excited to offer this awesome exhaust for all to enjoy.

Non-M Fitment:
Although we designed this exhaust specifically for the M3 model we felt it was a shame to rob this exhaust opportunity from the Non-M E36 owners. Face it, every straight six deserves a sweet exhaust. If you or your fellow enthusiasts feel so inclined our exhaust can be fitted to all standard 6 cylinder E36s. ** For non-m E36s you will have to slightly bend the exhaust hangers to get perfect fitment in the non-m rear bumper/diffuser. **

Why the upgrade?

By now your E36 M3 is approaching 30 years of age and you have a few possible exhaust situations:

- One of the options is you still have the factory exhaust and it is at the end of its life, it could be covered in rust and unsightly or packed solid with soot deposits which is not helping the weight, flow or tone of your exhaust.

- A second option is that you have an aftermarket exhaust that you fitted years ago and it is seeing the same fate as the factory muffler just at an expedited rate, the muffler is no longer sounding or performing the same and needs to be swapped out.

- Another probable exhaust situation you could find yourself in is that you have an exhaust fitted on your M3 that you think sounds good and had no intentions of changing it but after seeing and hearing our exhaust you find yourself wanting a new look, sound, and sense of enjoyment from driving your E36.

Supersprint makes one of the nicest, highest quality performance exhausts for the E36 M3 that we have seen. This exhaust functions more like a stock replacement sport exhaust than an aftermarket performance system. The sound is sporty and throaty but without attendant drama and over-powering sound. We like to say that it's a more mature sound than some other aftermarket exhausts which makes it perfect when included on an E36 M3 restoration or classic European tune. This Supersprint is all stainless steel and only bolts on to the Euro center section (OEM or Supersprint).

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust system because every aspect is done to such a high level. A Supersprint exhaust rewards you with a terrific sound, long lasting construction and excellent fitment. The Supersprint sound is very 'European' which fits the sporting sophistication of BMWs perfectly. Most systems are also modular - sections can be added or removed to custom tailor the exhaust sound to your preferance. Aside from 'Race' systems, their mufflers meet European noise laws so you get a refined and tuned sound without being excessively loud. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

This Euro center resonator replaces a stock European-spec center resonator or US/Euro catalytic converter section. The Supersprint exhaust piping is 60mm in diameter - 10mm larger in each pipe than a standard US exhaust system. This larger sizing helps to improve exhaust flow which frees up horsepower from the engine. Instead of working to push exhaust gas through small pipes the exhaust gas flows easier so the engine doesn't have to work as hard. Now constructed with 409 stainless steel piping!

The Supersprint Euro center resontor replaces a stock BMW Euro M3 center resonator OR requires the full Supersprint Euro headers and Euro rear muffler. For the best flow with supercharging or intricate intake kits, the Euro system works best!
