Transform your Mk4 Golf soundtrack and drivability with a premium catback system engineered for the 1J chassis 1.8 and 2.0 petrol models (1998 to 2004).

It is the ideal performance exhaust upgrade for anyone searching for a VW Golf MK4 exhaust system, 1J catback, back box upgrade, rear silencer kit or sports tailpipe solution.

Manufactured in 63.5 mm 2.5 inch pipework, this bolt-on kit runs from the cat to the tailpipe and replaces the mid section and back box. Choose your sound level to suit road or track use:

• Resonated centre section for a refined, subtle sporty note
