The combination of N52 and muffler delete surpasses all sound expectations from a small 1 series! Impressive direct-fit solution. With this new muffler/res delete you can completely transform the sound and driving experience of your 128. A simple installation that can be completed with hand tools gives you the ability to take your car to the next level at home in your garage! What sounds better than an in-line six-cylinder paired with a race-inspired exhaust setup, the answer is nothing. You have a nimble chassis fitted with an engine that provides more than enough power for spirited street driving or even taking to the track, if the exhaust is still factory you do not know what you are missing out on.
The ECS N52 Muffler & Resonator Delete removes the heavy, restrictive factory muffler and replaces it with a lighter weight, high flow, T304 stainless steel 3.0" exhaust tubing. This exhaust adds a louder exhaust note in a simple, cost-effective way without replacing the entire exhaust system and is fully compatible with the OEM rear valance. This upgrade creates a noticeable increase in exhaust sound, without adding significant drone at cruising speeds. As an added bonus, the ECS muffler delete shaves off about 16 lbs, weighing in at only 22 lbs. OEM units out of the 128 weigh in at around 38lb, a difference you will fully notice when upgrading your exhaust.

Replace the factory muffler and resonator for a race-inspired straight 6-cylinder sound
Large radius bends for maximum exhaust gas flow
16lb weight reduction (Factory 38lb, ECS 22lb)
Fits in the factory exhaust hanger locations
Installation instructions featuring locations for removing your factory exhaust
Design:
In-house designed and engineered rear Muffler & Resonator Delete is made of T304 stainless steel, 1.25mm wall thickness, CNC mandrel bent 3.0" tubing for straight-through exhaust gas routing
High-quality stainless steel
Barbed exhaust hangers tig welded into the factory location for direct fitment
Stainless steel accuseal exhaust clamps included for a leak-proof seal

In crafting this exhaust system, the 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. The ECS exhaust for your 135 incorporates this balance, offering a strategic blend of sportiness and practicality. Drawing from extensive experience, particularly with N54 cars like the E9x series, ECS has 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. This 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 the 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.
