How much do you guys think a custom 2.5" B-pipe without a resonator would run?? Shouldnt be too much should it?? arent the b-pipes straight? and with no resonator i mean its just like buying a piece of straight pipe right?? I do have a question about exhaust system modding though...ok when you guys buy JUST a 2.5" b-pipe (or anything else, like a 2.5" y-pipe) and add it to the STOCK system...how does that work??...isnt the stock system 2"??
