I have a few questions on the Magnaflow muffflers,I am looking at the round center/center ones 3" I.D Inlet and what's the difference on the outside diameter ones?There's 4",5",6" and 7",Is it the bigger the diameter the quieter it is?And the lengths? Same,longer the quieter?
I am thinking of using a 6" outer diameter that is 14" long round body stainless steel polished ones?:burnout:
