are the bands good enough or should i do the weld in bungs, i dont really want to take the y-pipe off again to weld on it since it is a p-i-t-a. I have slp y-pipe im hearing 4" does that sound about right? And i should be running max 1280-1290 degrees?
I am in the process of doing the same thing. Asked the same question on here and the general concensus for the most accurate reading is to weld them in.
