Sorry if this has been covered already, but haven't found too much. I'm a new Corvette owner, so please bear with me.

Car is 2000 base with 6-speed. Currently has intake and axle back exhaust.

I'm looking for the most complete header and x-pipe package with cats included. By complete, I'm referring to having all the necessary fittings for the EGR and Air pump systems and o2 sensors. Currently, from what I can find, Kooks is looking like the best option, but also quite $$. I'm ok with the money if that's the only good option. I hear a lot of folks like ARH and LG, but not sure if they include all the necessary fittings to make everything fit/work properly. Any advice is greatly appreciated. Cheers

 

Anyone able to chime in? Thanks in advance

 

Probably best to call the vendors and ask them directly.

 

I just did an American Racing header install on my 2003 c5. I bought the headers and catted x pipe kit and it came with everything except the gaskets to go to factory axle back. I did not use their header bolts as I had purchased arp bolts nor did I use the header to head gaskets as I wanted to use factory.
If you choose the headers with air fittings those gaskets are not included either. I used my original ones as they came off in one piece and worked fine.

I'm happy with the quality and ease of installation. I followed the instructions and did mine on Jack stands and had no issues. I did take my alternator off to give myself more room to work but the headers install from below so it's not necessary for install, helps getting old manifold out though.

I did have two issues though, I ordered headers with no air fitting and the front O2 extensions came for a C7. Sal from AR overnighted the correct extensions and I had been fretting about eliminating the air system anyway the only reason i was going to eliminate it was for ease of plug changes. I could have capped them but chose to hook it back up as I put in new plugs and wires so I'm good for a few years.

 

Thanks very much for the detailed response, I really appreciate it. Looking forward to some upgrades!
