Hey everyone got a pretty stock 98 gt and was wondering how much hp I could expect from bbk long tubes and a bbk off-road h pipe? Especially given that the stock midpipe has like 4 or 6 cats
You will definitely be freeing up some power with those exhaust upgrades,but I don’t imagine it will be a whole lot. Check out the ‘96-04’ section,see what all the mod motor guys are doing to add HP and feel free to start a thread there,you will get some good advice and answers for any questions you have .
