VW Golf Mk4 1.9 TDI (1J) 1998-2004 Cat Back/Cat-Back/Catalyst Back Performance Exhaust System 63.5mm (2.5") | Resonated & Non-Resonated | Mid Box/Centre Silencer Delete | Sports Back Box Tailpipe Upgrade Diesel PD Turbo | Golf IV 1.9 TD

Unlock a deeper diesel tone and a cleaner, sportier finish for your 1998 to 2004 Volkswagen 1.9 turbo diesel with this premium rear system upgrade. Designed to run from the catalytic converter to the tail end, it replaces both the centre section and back box for a sharper soundtrack and a tidy OE-plus look.

Built in 2.5 inch 63.5 mm pipework, this system is available in two sound levels to suit how you drive:

• Resonated setup includes a centre silencer for a refined, subtle yet purposeful note on the road.
• Non-resonated option removes the mid silencer for a louder, sportier exhaust note.

Everything you need to install is in the box. All relevant fittings and gaskets are supplied for a straightforward fitment from the catalyst back.

We have fitted this system in-house and it delivers exactly what owners of the 1.9 turbo-diesel want: smart looks, a noticeable step up in character, and excellent fit. Our customers love the quality, the sound options, and the way it transforms everyday driving without fuss.

Please note: some cars will require the 4Motion rear valance for the tailpipe cutout. Genuine VW part number 1J6807521C can be ordered from your local Volkswagen retailer.

Why choose this upgrade

• Direct replacement for centre and rear sections from the catalyst back
