This Audi A3 TFSI 3-door performance exhaust is made in 3"/76.2mm pipework and fits from the turbo backwards (Turbo back system) these exhausts replace the front pipe, standard catalyst, centre and rear sections.
The de-cat sports exhaust option is sold for motorsport and off-road use only and will NOT be able to pass a UK MOT emissions test or police roadside checks. The high-flow sports cat version will enable you to pass a UK MOT emissions test or police roadside checks.
The non-resonated option makes the system louder as it excludes the centre silencer and therefore, has a sportier exhaust note. This exhaust is also available as a resonated version (including a centre silencer) which is a quieter option.
All relevant fittings and gaskets are supplied.
Note - Some of the fitted images may show alternative parts.
