Stainless Steel 3" Catback Exhaust Kit for VW Beetle / Golf GTi /Jetta MK4 (1999-2004) 1.8L Turbo

Cat-Back Exhaust System for VW Jetta MK4 1.8L (1999–2005)

Transform the driving characteristics and auditory profile of your MK4 with this precision-engineered exhaust system. Designed specifically for the 1.8L turbocharged engine, this upgrade replaces the restrictive factory exhaust to allow for a faster, more efficient exit of spent gases. By reducing backpressure, your engine can breathe more freely, resulting in improved horsepower, better fuel efficiency, and a more responsive feel across the entire RPM range.¹

The system is constructed with 2.5-inch outer diameter (OD) piping that has been mandrel-bent. Unlike traditional crush-bending, which can create bottlenecks, mandrel bending maintains a consistent internal diameter throughout every curve. This ensures a smooth, laminar flow that maximizes exhaust velocity and optimizes turbo spool-up time. The dual T.I.G. welded construction provides exceptional joint strength and durability, ensuring the system can withstand the vibrations and thermal stress of spirited driving.²

At the rear, the system is finished with a striking 3-inch dual-tip configuration. The tips feature a polished finish that perfectly complements the classic lines of the MK4 chassis, providing a refined yet sporty aesthetic. Beyond the looks, this setup delivers a deeper, more resonant exhaust note that highlights the unique sound of the 1.8L engine without being overly aggressive for daily use.

Designed for versatility, this system is compatible with all drivetrain and transmission configurations, including both automatic and manual models. The kit includes the necessary hardware shown to facilitate the upgrade, ensuring you have the essential components to transition from your stock setup to this high-flow alternative.

Because this system involves precise fitment and exhaust alignment, professional installation is recommended to ensure optimal clearance and a leak-free seal. Once installed, this upgrade serves as a long-term performance investment, backed by a manufacturer’s limited lifetime warranty against defects.
