Milltek Audi RS3 8V Sportback Performance Cat-Back Exhaust (Pre-Facelift) - 3in/76mm, Valved or Non-Valved, Resonated or Non-Res, HollowTek, EC Approved Options, Cerakote Black or Polished 150x95mm Oval Tips - UK Made

Audi RS3 8V Sportback Pre-Facelift Cat Back System by Milltek - UK Built Stainless Performance Exhaust

Give your RS3 8V Sportback the soundtrack and response it deserves with this British-built Milltek rear section upgrade. Precision mandrel-bent 76.20 mm pipework, beautifully finished oval tailpipes and options for valve control and sound level deliver a premium result that looks right, fits right and sounds incredible. Choose quieter or louder setups, valve-integrated or fixed-flow, plus Cerakote Black or mirror polished 150 x 95 mm ovals. EC compliant variants are available for road use where applicable.

Developed and manufactured in the UK, this system is a direct-fit replacement for the pre-facelift RS3 8V Sportback. HollowTek rear silencer technology on applicable versions gives a deep, refined five-cylinder note without unwanted drone. We have fitted these on customer cars at MJ Modifications and feedback on tone, build quality and alignment has been consistently excellent.
