Hi, I'm looking to replace the exhaust on my 2019 cupra ST and was wondering a few different things. Is it possible to fit a pre gpf downpipe so i have the cat but no gpf, while ofcourse mapping out the gpf? Also, is a aftermarket system like the miltek catback from a golf r estate compatible on a cupra? And lastly, I have heard that you should go stage 2 to do a gpf delete, but I'm wondering if its safe for the car to only go stage 1 and then do a gpf delete and they maybe add on a sports cat? All help will be appreciated
