ok thanks

so my idea is to make straight pipes from the downpipes by cutting out the secondary cats and replacing them by 2 pipes and then in the muffler I would have to close the bypass pipes with a metal plate on each side and for the left muffler I`ll have to replace the small muffler inside by a single pipe.
This way the german cops should not be able to see that I have no mufflers and I still can drive with straight pipes

is that correct?

Thanks guys,I really appreciate your input!
