What is an axle-back exhaust system?

An axle-back exhaust system replaces the muffler and the pipes extending from the rear axle. It's a simpler exhaust modification compared to a cat-back system, primarily focused on changing the sound and appearance of the rear of the vehicle.

Will this exhaust make my car much louder?

This Remus axle-back system is designed to provide a sportier and deeper exhaust note than the factory setup. While it's more engaging, it's generally not excessively loud for daily driving and aims for a balanced sound.

What material is the exhaust made from?

The exhaust system is constructed from stainless steel. This material is chosen for its strength, resistance to rust and corrosion, and its ability to withstand the high temperatures of exhaust gases.

About this part

Product Details

If you're looking to give your 2011 BMW 1 Series F20 or F21 with the N13B16 engine a more engaging exhaust note, this Remus axle-back system is a solid option. It replaces the factory muffler section, letting you hear more of the engine's character without being overwhelming for daily driving. This is a popular choice for owners who want a noticeable improvement in sound and a sportier feel.

Remus builds this system from stainless steel, which is well-known for its resistance to corrosion and its ability to handle the heat cycles an exhaust system goes through. The design focuses on improving exhaust flow compared to the stock muffler, which can contribute to a slightly more responsive feel. You'll notice a deeper, more resonant tone, especially when you accelerate. The installation is designed to be a direct bolt-on replacement for the original muffler, meaning no welding or cutting is typically required, making it a straightforward upgrade for many DIYers or a quick job for a mechanic.

This axle-back system is designed to fit specifically on the 2011 BMW 1 Series F20 5-door and F21 3-door models equipped with the N13B16 engine. It's a well-made component that offers a good balance of improved sound and build quality for your vehicle.
