BMW Exhaust Parts, Mufflers & Catalytic Converters for BMW 3 Series E30 (1984-1991)

Born from our own experiences and profound love for the E30, each aspect of our exhaust was designed to enhance your E30 experience. Introducing our revolutionary E30 Exhaust for the 325, an exhaust option that redefines performance and style. Crafted to be lighter, bolder, and more efficient, this exhaust system is designed to make a statement on the road.

Our exhaust is all about making life easier. With factory-style flanges that bolt straight onto your existing converter, you won't be wasting time or cash on complex installations. And those angled slash-cut tips? They're not just for show, they're a statement, blending style with a hint of attitude.

Engineered for maximum enjoyment, this exhaust system boasts dual 2.25” mandrel bent stainless steel tubes, ensuring a smooth flow path for optimal efficiency. The result? A growling, low-toned exhaust note that's music to your ears and a nod to German engineering at its finest.

Our E30 Exhaust doesn't just enhance performance; it's also designed with practicality in mind. Featuring period-correct styled exhaust tips, increased exhaust pipe diameter, and an upgraded center mounting solution, every detail is crafted for perfection.

This exhaust system retains factory flanges and hanger locations, ensuring a seamless fit and easy installation process. Plus, with a Helmholtz resonator strategically integrated to mitigate drone around 2200 RPMs, you'll enjoy a refined driving experience without sacrificing performance.

Tired of busting your knuckles from old hardened exhaust hangers?

This Schwaben tool removes the hanger by pressing on the steel hanger bracket and pulling the rubber hanger in one motion. Self centering force pin locks onto the pin while the flat paddle pulls off the rubber hanger from behind. Slim profile and a 25 degree offset works in tight areas.

Achieving precise exhaust fitment can be tricky—especially when the exhaust hanger has room to slide. This movement can cause annoying rattles or even lead to contact with the underbody or rear bumper. The ECS Tuning Exhaust Locking Collar offers a simple and effective fix. Designed to clamp securely around the exhaust hanger, this collar keeps everything firmly in place, eliminating unwanted movement.

Crafted from high-strength 6031 billet aluminum and finished in a sleek black anodized coating, it delivers both durability and corrosion resistance. With this collar in place, your exhaust stays exactly where it should—no rattles, no surprises.

Product Design:

Made from precision machined 6061 aluminum Black anodized finish Stainless steel M5 X 0.8mm hardware Installation & Support:

Install the locking collar around your exhaust hanger, position the hanger in place, and snug the locking collar down in place against the hanger! ECS Exhaust Hanger Locking Collars are available for 10mm and 12mm exhaust hangers. Please measure your hangers before ordering. The 12mm locking collar can be found HERE.
