..as i originally stated, I couldnt afford to pay a shop all the labor involved in removing a rusted-in torsion bar AND Tranny crossframe JUST to make ROOM to remove/replace a COMPLETE exhaust assy, Y pipe to rear of Cat. converter-Chevy thought 1 piece exhaust was a better idea..... I wasnt throwing any codes to say the cat was bad and I live in a county where emissions testing isnt a law-all I had was a rusted out Y pipe next to the O2B2S1 area, hence why I went the route I did...sometimes an empty and un-fillable wallet trumps brains ;-)how many miles are on your S10? after 100k they recommend replacing the cat. And here you have one ready to go. Seems a no brainer to me.
