well for xmas i could either order parts for my bird or the 53 . seeing as right now the lx is my daily , i ordered the parts left to do the brakes and an exhaust kit from mandrel exhaust systems to put duals on the car . my question is how far off is it going to throw the 'putor off for now if i run true duals with the cats in place and probably no mufflers ? right after the silly season the cash we'll be a little restricted or i'd order up a 4 bank chip from blue oval chips with the parameters i need , but i'm just going to have to drive it for a bit for now .......... unless it's going to cause a major issue . if i got any change left i'm gonna order up a set of them used pi cams from nick ............. then ....... d-m- i seem to spend so much cash on these mechanical contraptions of mine ....................
