This looks promising.
Does deleting the Back box not cause the car to fail its MOT on emissions? Is it really just a redundant part?
It isn't redundant as such, it's purpose is to remove noise, but because it is after the cat it will have no effect on emissions. I wanted the PE as it does sound awesome but for my car they don't list it for a manual on EPC which is annoying, but I will try and recreate that sort of sound from my longlife system
