Alrite. Well i just ordered a 18 inch glasspack be here first thing in the morning but cant weld it on til monday morning so.... but another thing.... what if i used a smaller diameter pipe? Like say 2.5 or smaller? What would hwppen from that? Single exhaust also?
^^^Not much IMO with a stock engine...some folks would argue back pressure issues, but on a stocker, you're not going to notice any discernible difference except for in sound from your exhaust.
got my glasspack in this morning. put it on both ways and revved it up, ima say i like the forward sound that also convinced my bro to get rid of his magnaflow and get a glass pack. weld coming soon thanks fellas
