Having put my deposit down on the new RS3, my wifes 2018 TT-RS Cab will be going up for sale shortly. Trouble is, I'm not sure if I would be better taking it back to stock and selling the tuning parts or leave it as is. Its got the Wagner EVO3 Competion kit with the big intercooler and racing cats system which was about £3k and then its got the Forge hardpipe and intakes I believe (can't put my hand on the invoice at the moment). It might cost me around £250 to remove it but whats this kit worth second hand I wonder? Will the TT be worth more with around 510bhp and the glorious pops and burbles? Even Audi just MOT'd it with the racing cats (they did wonder why it didn't sail through the emmision but good to know it passed with them). Obvioulsy got the hasstle of removal with day off work etc too.
