We understand the desire for a thrilling exhaust note without the annoyance of highway drone or interior vibrations. This ECS exhaust for your 335 incorporates this balance, offering a strategic blend of sportiness and practicality. Drawing from their extensive experience, particularly with N54 and N55 E chassis, they have engineered an exhaust packed with innovative features, compatible with factory and aftermarket downpipes.

Prepare for a fresh new exhaust, things are about to get rowdy. This ECS exhaust features twin 2.5" brushed pipes with flanges that bolt directly to your factory and aftermarket downpipes.

Replacing the large suitcase muffler is a pair of 2.5" turbo-style mufflers that shed weight and give a signature sound. The turbo-style muffler features an inner design that refines the exhaust note to perfection. An extraordinary mixture of both volume and frequency.
