Pulse-TIG robotically welded from billet 304 stainless steel, the PERON de-cat downpipes deliver an aggressive, purposeful sound but with no annoying drone while cruising.
A STG2 ECU remap is required to optimise the performance of the engine with the less restrictive, freer flowing downpipes. This also removes any lambda associated "check engine" warning lights. Combined with a remap, you will experience significant performance gains.
A lot of time was spent perfecting the acoustics to enhance the sound of the RS6's incredible V10 engine. These downpipes can also be fitted to cars with the stock cat-back exhaust system or other aftermarket cat-back systems.
PERON accepts no responsibility for the use of this part on the public highway where removal of emissions controls is prohibited. It is the customers responsibility to ensure they comply with rules and laws relating to their home country.
