Audi TT RS (MK3) 2.5 TFSI Secondary De-Cat Bypass Performance Exhaust
This Audi TTRS performance exhaust is made in 2.5″/63.5mm bore pipework and replaces the secondary catalyst (Cat Bypass).
This de-cat sports exhaust is sold for motorsport and off road use only and will NOT be able to pass a UK MOT emissions test or police road side checks.
All relevant fittings and gaskets are supplied.
EML lights may activate after removing the standard O/E catalyst. An ECU Re-map is recommended to correct this problem and stabilise all power increases.
