[QUOTE="jeepjoe43, post: 430116, member: 19255"] Well, that it definitely shot! The Rock kit did NOT require welding, all bolt in. The cat was not part of the pipe and muffler kit and had to buy it separately (still figured in to my overall cost). For me it was an easy install, but I had mine on a lift with the skid pan and T-case out. This all happened in the middle of my SYE install, clutch, gas tank and D35 replace. Might be easier to just take it to a shop if it's worth it not to do the job on the ground. If you have just one sensor, the bung for the O2 sensor on the Rock stuff head pipe will be there but the pipe will NOT be drilled. I guess that's so it fit's later models with multiple O2 sensors fore & aft of the cat? I don't know which yours is. Thought mine was the latter and bought 2, but it ended up having just one. Anyway, I didn't discover the pipe on mine til I had it in, and I decided to just pull the plug in the manifold and put it there. Now I occasionally get code 52 (lazy O2 sensor) may have something to do with that. You wouldn't think moving the sensor 4" would make any difference. Tip, get all new nuts & bolts for the head pipe and the cat. I found mine at ACE, and it saved a lot of headache. [/QUOTE]
