You can use the Y-pipe, but the Emissions legal headers for the 98-00 have provisions for AIR and EGR. 01-02 headers only heve AIR. Bolt patterns are the same though. Try to buy application specific parts to avoid problems with AIR flanges not lining up. Or you can buy the race ready headers which don't have AIR or EGR.

they will fit , but you'll need to get a plate to block off the EGR. I'm not sure if the AIR will line up either. You could just block them off and have the codes deleted. They will bolt up to the 01-02 LS1 head though. The Y should fit also.

straight from the guide
7) If you want to swap 98-99 and 00-02 headers around you'll need to remove your Air system or purchases the Air tubes from the year the headers were made for since the 98-99 and 00-02 have different Air tube setup.
8) It should go without saying but if you want to swap 01-02 headers on your 98-00 you'll need to remove you EGR system.
9) 00 are an oddball year as the EGR and Air setups are different then the 98-99.
10) When removing the Air system on the 00+ cars you'll be left with a vacuum hose that you'll need to plug up.
Buy your headers with some kind of ceramic coating or get stainless steel. If you cant afford coated headers hold off until you can. If your car see's alot of winters (real winters; i.e. east coast and mid west, ect) you might want to seriously consider the stainless steel headers, they are more expensive then ceramic coated headers but the chance of rust will be greatly diminished.
