Key Features:

Catless Design for Maximum Flow
The catless design removes the restrictive factory catalytic converter, allowing for a free-flowing exhaust path. This results in reduced backpressure, improving turbocharger efficiency and overall performance. Perfect for high-output builds and those pushing their BMW to new heights.

Quicker Turbo Spool & Increased Power
With the reduced backpressure, your turbocharger will spool faster, providing quicker throttle response, reduced lag, and a noticeable increase in both horsepower and torque across the RPM range. Feel the performance boost whether you’re accelerating off the line or making those high-speed passes.

Aggressive Exhaust Tone
The catless setup brings out a raw, aggressive exhaust note from the N20 engine. Expect sharper turbo spool, louder pops, and crackles on lift-off, along with a growling sound that’s sure to turn heads. It’s performance and sound, combined.

Durable Stainless Steel Construction
Constructed from high-quality 304 stainless steel, this downpipe is engineered to handle high temperatures and provide long-lasting durability. TIG-welded for strength, and precision CNC-machined flanges ensure a leak-free, secure fit.

Direct Bolt-On Installation
Designed for a hassle-free installation, this downpipe bolts directly to your stock turbo and exhaust system with no need for modifications. Get maximum performance without the need for welding or additional custom work.
