Description

Upgrade your VW Golf MK4 1.8T with the Untd. Performance Catless Downpipe—engineered to dramatically increase exhaust flow, boost turbo efficiency, and deliver a raw, motorsport-inspired sound. Designed for performance enthusiasts and built to handle the demands of tuned or track-driven setups, this downpipe removes the factory catalytic converter, opening the door to quicker spool, higher power output, and an aggressive exhaust tone that brings your 1.8T to life.

Whether you’re preparing for a Stage 2 tune or just want to wake up your daily driver, this is the first step toward serious performance.

Key Features:

Catless Design for Unrestricted Flow
The fully catless configuration eliminates the factory catalytic converter, significantly reducing backpressure and allowing your turbocharger to breathe freely. The result is faster spool, improved throttle response, and increased horsepower and torque across the RPM range.

Enhanced Turbo Sound and Exhaust Note
With the restrictions removed, the exhaust tone becomes noticeably louder and deeper. Expect sharper turbo spool sounds, aggressive crackles, and an unmistakable growl under throttle—ideal for those who want their MK4 to sound as good as it performs.

High-Quality Stainless Steel Construction
Crafted from T304 stainless steel, this downpipe is built to endure high exhaust temperatures and resist corrosion. Precision TIG welding and CNC-machined flanges ensure a perfect fit, maximum durability, and leak-free performance.

Bolt-On Fitment
Designed for a straightforward installation, this downpipe is a direct bolt-on replacement for the OEM unit on the MK4 1.8T. Compatible with factory or aftermarket exhaust systems, it includes necessary hardware for a smooth install.

Compatibility:

• Volkswagen Golf MK4 1.8T (1999–2004)

• Also fits VW Jetta MK4 1.8T, Beetle 1.8T, and other models equipped with the EA113 1.8T engine

If you’re ready to unlock the true performance and sound potential of your MK4 1.8T, the Untd. Performance Catless Downpipe is the upgrade you’ve been waiting for.
