Performance rear exhaust system for BMW 1 Series E82 118d and 120d M Sport (2008+)

Transform the character of your diesel coupe with a British-made T304 stainless rear system engineered specifically for the BMW 1 Series E82 118d and 120d M Sport. Crafted in the UK from premium austenitic stainless steel with precision mandrel-formed tubing, this upgrade delivers a cleaner, richer tone, sharper response and superb long-term durability while keeping cabin noise civilised on the motorway.

If you are hunting for a BMW E82 diesel exhaust upgrade that fits right, sounds right and lasts, this is the bolt-on solution from the catalytic converter back. It retains all factory emissions equipment and uses carefully selected bore sizes to improve flow without hurting mid-range drivability. Expect a deeper note on throttle and refined manners at cruise with no unwanted cabin boom.

• Constant-radius mandrel bends preserve gas velocity for responsive turbo-diesel performance
