Hi, I've been searching for a resonator delete to my "new" Seat Leon Cupra 280 ST (estate) for a while. I found a lot of dealers for the 290hp version but my local Seat dealer told me that there is some difference between those exhaust systems but couldnt tell me exactly what. Do you guys know? Any suggestions were, or even better a link, to a dealer? Your own experience for a mod like this? /Best regards
