for my 91Z, 5.7 TPI... everything is still stock, BUT i have SLP headers and F'Master cat-back to put on it some day. right now, one of the cats is fubar'd (dual cats), so i'm thinking about going ahead and putting on the cat-back and new cats, saving the header install for later. my "plan" was to rebuild the engine one day and do it all then, but i don't want to replace another "factory" type cat now, and then again later with something else. so... bottom line is, if i go ahead and put on the cat-back now, which type cats do you guys recommend? i'm gonna be gone for a couple of days, so i'll check back in when i get back and see what y'all say...
