anyone know what a stock used exhaust from a 337 goes for? i think he has everything from downpipe back, i just need the very end. i have a 337 rear valence i'd like to put on my golf. there's a local guy on vortex selling one but he doesn't list a price, he asked for offers. i offered $50 and he said they go for more than that. what's a fair price?

is it any better than a stock 1.8t exhaust?
