Evening! I have acquired a stock Leon Cupra ST catback which I want to modify to get a louder exhaust. I have now opened the rear mufflers and the insides look like these. What would you guys do to the piping? I'm thinking about doing it like it is in the Golf R variant, so otherwise an straight pipe but it has a slit in the middle chamber inside the muffler. Might be hard to weld that in though. I'm not looking for a complete straight pipe, but would like something louder like the Golf R for example.
