Milltek Non-Resonated Cat-Back Exhaust | VW Golf MK4 337-Single GT100 Tips

Description

The Milltek Non-Resonated Cat-Back Exhaust System is engineered specifically for the Volkswagen Golf MK4 337 Anniversary (180 bhp). This is a direct factory replacement that bolts to OEM hangers with no modification required. Constructed from T304L stainless steel and mandrel-bent throughout, the system features a 2.50" primary pipe diameter and CNC-formed GT100 single exit trim. The non-resonated design eliminates the OE resonance chamber, delivering a pronounced, full-throttle exhaust character without drone at cruise. Dyno-tested to support gains across the rev range while maintaining street-legal operation.
