In crafting our exhaust systems, our primary focus is on achieving the perfect balance of sound and comfort. We understand the desire for a thrilling exhaust note without the annoyance of highway drone or interior vibrations. Our exhaust for your 135 incorporates this balance, offering a strategic blend of sportiness and practicality. Drawing from our extensive experience, particularly with N54 cars like the E9x series, we've engineered an exhaust packed with innovative features, compatible with both factory and aftermarket downpipes. Experience the perfect blend of performance and everyday usability.

Prepare for a fresh new exhaust, things are about to get rowdy. Our exhaust features twin 2.5" brushed pipes that slip fit and clamp onto your factory midpipes. The dual 2.5" mid-pipe adapter converges into a single 3" section heading toward the rear axle. The 3" exhaust section snakes through the rear section of the car making smooth dips and curves to make its way into a light-weight 3" turbo style muffler. Don't be fooled by our 135 muffler, the size is nothing but deceiving. The turbo-style muffler features an inner design that refines the exhaust note to perfection. An extraordinary mixture of both volume and smooth frequency. Paired with the 3" muffler is a set of 3.5" chrome exhaust tips that give your rear diffuser a sporty look that shouts performance.

E8x M-Sport Rear Diffuser - Gloss Black

Introducing our rear diffuser designed exclusively for your 1 Series – a perfect intersection of aftermarket and factory styling. Rarely do you find a design that not only encapsulates every curve and contour of a vehicle but elevates its overall aesthetic with a single, impactful addition. There are limited aftermarket options available for the 1 Series, our engineers have risen to the challenge of providing aftermarket support for these perfectly sized vehicles starting with this one-of-a-kind rear bumper upgrade.

Our diffuser replaces the mundane factory M Sport diffuser with a perfectly fitting alternative, designed to enhance the rear end of your 1 Series. Using the existing factory hardware and tab mounting locations, a transformation is merely a few screws and a plastic trim tool away. During the prototype phase, we achieved an impressive fit and finish, but our commitment to excellence led us to make further refinements. With our updated design, the ECS diffuser is now polished to perfection, an indication of the time and effort we invest in each product.

Installation is a breeze, requiring no drilling, cutting, or modifications of any kind. Simply remove your current valance, align the tabs, and effortlessly secure the diffuser in place using the factory mounting locations and hardware. Ensure a snug fit by verifying the alignment of all tabs, and with a gentle press, witness the tabs seamlessly click into position.
