I have an 87 gxl. I have a k&N filtercharger system on my 7 and thats the only performance mod so far. I am pretty even with my buddy's 97 bone stock accord. I find this pretty sad considering i'm even with a mid-sized stock honda. I'm on the verge of crying. What kind of mods can i apply to my car? What exactly is porting, and where can i get it done? (i'm up here in canada, eh)... as well, what's the most cost effective bang-for-the buck exhaust system that i can bolt on? Should i get a catback first, headers, or cat replacement pipes? will they bolt on to the rest of my stock exhaust? (waste, yes, i know). Please lemme know what i can do. Thanks!
