high flow header = extractors
just do the full exhaust 1st and see how you like it. you never know, that could be enough for you???
also - a few thing you may wanna check are your plugs, leads, dissy and coil condition. if any 1 of these are not working properly, it means less spark and less power.
you have a 97 right? what suspension are you running? ages of suspension conponents are?
