I am planning to install pacesetter longtube headers on my car (1998 Z28). I have already purchased plugs and wires to replace during the install. What should I plan on purchasing in addition to the longtubes, plugs, and wires during this process. I know lots of people have done similar setups, does anyone have an idea what total cost would be? Thanks for your help in advance!

I think you are ready to go. I have pacesetters waiting for install and i heard the copper gaskets work well.

poly engine mounts, they are easy to do when the headers are out already.

gm steel gaskets, o2 sims, o2 extension harness, egr delte, and u already have plugs wires during the install of the long tubes this is what usually alot of people do.....anything else will be a lid if you already dont have one, tb, i would get it tuned...goodluck...

Thanks a lot for all of the great responses! What is involved with doing the o2 sims, o2 extension harness, and egr delet. I have never installed a set of longtubes so I'm pretty new to all of this. I feel like I can install the headers, I'm just unsure about how to do the rest. Thanks again for all of the help. I would not know half as much about my car if it wasn't for this site and everyone being willing to help and share knowledge.

I would forget about the o2 sims and the extentions, they are a waste of $$ IMO. I would just go to a shop that can tune out the rear O2 codes and have them deleted, its likw $20. And as for extentions I would just cut the wire on the O2 and extend it yourself using wire and solder, make sure it is a good connection. People say not to do that but i have always done it that way and I have never had the infamous O2 switching code issue. I been rocking the same home extended O2 wires for a few years now and it works fine for me.

I agree, definitely save yourself the headache and do poly motor mounts when you have the headers off.
