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 your choice of 3.5" exhaust tips that give your rear diffuser a sporty look that shouts performance.
