2.5″ De-Cat Downpipe Kit for BMW N13 Engine – Performance Upgrade for 1 & 3 Series (F20, F21, F22, F30)

Upgrade your BMW’s performance with this high-quality 2.5-inch de-cat downpipe, designed specifically for the BMW 1 Series (F20/F21) and 3 Series (F22/F30) with the N13 1.6T engine (114i, 116i, 118i, 120i, 316i, 318i). This downpipe is engineered for maximum flow and performance, making it a perfect choice for enthusiasts looking to improve turbo response, horsepower, and exhaust sound.

Constructed from acid-resistant stainless steel using precise CNC manufacturing, this de-cat downpipe eliminates the restrictive factory catalytic converter. Removing the CAT significantly reduces exhaust back pressure, resulting in faster turbo spool, increased power output, and a more aggressive exhaust tone.

Key features:

• 100% de-cat design – no catalytic converter

• Made from durable, acid-resistant stainless steel

• CNC machined for perfect fitment and performance

• Optimized for smooth exhaust gas flow and minimal turbulence

• Ideal for upgraded or performance turbos

• Enhances engine power, throttle response, and sound

Installing an aftermarket downpipe is a crucial step when upgrading your turbo system, ensuring you’re not bottlenecking your turbocharger’s potential. This downpipe is also a cost-effective upgrade for stock setups, delivering noticeable performance improvements without the high price tag.
