Also asked some prices from Martelius, exhaust system company here in Finland, how much costs custom exhaust system built to 1.5 TSI EVO since noone makes anything yet. They applied me that stainless system:
Downpipe 700€ + CAT of my choice 179-415€ and cat-back 1000-1200€ depending of tailpipes. But since 1.5 evo has these fake outlets.. dunno about tailpipes then or can those be modified to actually work.. will see hehe
