Moin Moin, I ordered a Seat Leon ST cupra 290 at the end of September. At this time I didn’t think it was clear that the cupra 3/5 doorr was getting a new exhaust system. However, the ST station wagon was not. The reason for this is that it was too loud in the interior during the tests and you don’t want to “dry” the passengers. I’m very disappointed that they installed a class exhaust system with the other two variants of the Cupras and that the ST did not !!! Since for me an almost 300hp strong car should sound accordingly. Here now my question: Do you think if I talk to the Seat dealer, that I would have an additional flap exhaust system installed (by Seat) that it is possible to keep the new car warranty? Had seen a super flap exhaust system from the company JE DESIGN. I find that sounds really great and has decent quality in my opinion. MfG Cupracer93
