i'm getting ready to do the emmissions test. right now i have my off-road h-pipe on there. as well as my other mods below. i need a h-pipe or even an x just for the emissions test. i just need one. where's one i could get dirt cheap or could i just put them on my h-pipe?
 
do u have that square metal tube brace that basically goes underneath the entire front end? my 97 does. my header rubs on it alittle. so what i did is i fabricated it for about 10 min with a grinder and problem solved. It really opened up the car right from the get go. alittle costly to do it though.
