got a brand new still in the box set of jet hot long tubes for sale on ebay for 375$. That's very cheap considering they are a good 500$ shipped usually. Plus I will fed ex them to who ever wins the auction. My ebay user id is edrl1970. thanks.

those rubber hoses are the AIR system and are needed to pass emissions, EGR is a must to pass as well and cats will need to be placed on the system somewhere, i just passed with the pacesetter LT's with a single cat just after the y-pipe

neither the air pump nor the egr is necessary to pass emissions. air pump is to help the cat when its cold (from what ive heard most dont work anyway) and as long as you have a 3 way convertor it should take care of NOx (the reason for the egr valve). I have Kooks 1 3/4" offroad lts with their catted y and the ory. With the catted y on I passed the sniffer earlier this week. As long as your car is running right the 3-way convertor will be good enough. Kooks also sells emission legal lts

I live in an area with visual emissions inspection only and I have Kooks stepped stainless with AIR and EGR fittings...Quite possibly the nicest header I have ever used...Worth the $$$...

sorry didnt notice you had a 97. why dont you just go full off road and run sims? a tuner should be able to get you to pass the readiness test. a simple clamshell could work if you have visual inspections as well.
