i just got my slp long tubes today and am about to pay for the install. I was wondering if i need anything else at all to do the install? i have a 97 gt, auto. I already have the slp o/r xpipe so that shouldnt be a problem with buying a whole new xpipe. I was reading somemthing about some kind of 02 extension things?? do i need that for my car, because the one they sell on here is only for the 2004. Okay guys thanks

 

02 ext are a yes... and i don't think the x pipe will work someone else needs to chime in on that as i don't know bout slp.... also go ahead and buy the ford header gaskets...

 

well the longtubes came with an installation kit which include a 12" 02 extension, and 2 header gaskets..oh yeah it also came with plenty of bolts.is that everything for the install?
