I'm Awesome
My 1990 C1500 got really loud, fairly quickly, and it was running like crap. Stalling and stumbling. The Y-pipe was blown out right by the O2 sensor and the Cat, the 33 year old one, was pooched.
Living in Ontario, Canada, I wasn't looking forward to the job, but I bought a stud puller, and to my complete amazement, it rattled the studs out of the manifolds. I thought I would be taking them off and drilling them out for sure.
I got a new Y-pipe from a local source, along with new studs and I ordered a new cat on line.
Again, by a stoke of luck, the new cat had 2 1/2" inside diameter so it slid right on the new Y-pipe. The new cat is shorter, so I went to the local muffler shop and bought a 19" piece of 2 1/2" pipe and it slipped right into the cat, and with a little persuasion, into the stock intermediate pipe, which is not that old. It's nice and quiet now and running a whole lot better.
