i want to get a universal backbox what size does the end need to be to go over my exhaust??

would advise a whole system if u running a diesel m8, in my opinion its a waste of time fitting one with just a back box

u still didnt answer my question i know what im doin lol
the system will come soon enough im going to make it myself!
