Depending on which brand you prefer. DO NOT GET HEADMAN!!!! I dont care if someone says they had a good deal with them blah blah blah. It will come back to bite you in the *** later down the road. JUNK. I like Hooker headers. Get them coated and they will dress up your bay, give you nice sound and add "roughly" 15 horsepower back to the car.

Hooker 2149 (with O2 bung, AIR pipes, and EGR, ceramic coated) I HIGHLY reccomend these. Everything works out and is provided. If you are a do it yourselfer, I have instructions on how to install headers if you would like. Hooker 16720 Y-pipe can be used with either.**New y pipe for headers**Good luck.

Deleting AIR:

Alot of the manufacturers of headers make a set with the AIR pipes deleted. As I said above, AIR only functions on startup until the engine is warm, so you can safely remove it with no ill effects to emissions testing (provided you get the sniffer done when the engine is hot). You can cap off the lines on the headers or not, as the valves are supposed to be one-way only, likewise for the main cat. The AIR eliminator kit sold by many magazines does NOT give you any power, as the AIR pump is a fairly freely-spinning unit, but it does clean up the engine a bit and so is mostly a cosmetic mod. Any connections can be left alone as the L98 does not throw codes when AIR is removed.

Catback:

Any of them should give the same 10-12hp gain. They all vary depending on the sound, shape, looks, ect.Corsa is best for those who do not like resonance (loud droning sound at around 2000rpm usually). There are many brands. The top ones that I reccomend are: Corsa, Borla, B&B, Flowmaster is good for sound but has low flowing capabilities and bad resonance.
