Ok im getting different answers from different people on this... but here is the problem im stuck with.. ok well in spring i am getting these parts installed Pacesetter headers with Y-pipe with 3" Outlet then Pacesetter high flow cat 3"in/out I-pipe stock is 2.25" want to replace that but am having trouble choosing between 2.75" or 3" because of torque loss and back pressure, then to a Flowmaster 80 series muffler with stainless steel tips.. now another problem i have is that the high flow cat is like half the size of the stock one.. so i will have a hugge gap there and was thinking maybe could just throw a cutout there or just weld some pipe from i-pipe to the cat.. so if you have an opinion on what i should do i would appreciate it
