Hi guys im just new to the forum and recently bought a 2016 rs3 , looking to try get 420ish bhp and a bit of deeper tone to exhaust. Was thinking of stage 1 and secondary decats. If i get a decat downpipe to remove the main do u need stage 2 software and the rest of the hardware to match?
Any help is appreciated.
Thanks .
