I have a stock 97 z28 and I want to get coated pacesetter longtubes and a borla catback for it. I live on long island new york so I need to pass emissions so im going to get the headers with emissions. If I could I would like to just get the ory pipe with no cats. Im not sure if I will be able to pass inspection with no cats I think they just plug it in and there is no visual check so would i be able to pass with no cats? Would you recommend I get the pacesetter y pipe? I don't really understand the AIR and EGR so what do I have to do when installing the headers. Also what is everything I will need for installation? Thanks

 

My catalytic converter has bolt-on flanges on both sides, so when its time for emission testing i unbolt the off road(straight) pipe and rebolt the cat back on. My car has passed without the cat on but one year failed because the guy actually did a visual test. So now every year, i just bolt it back on and use an RTV sealant on the flanges, to prevent exhaust leaks. I did run into ground clearance issues going over speed bumps but a cut of grinder and a drill press solved that problem.

 

Your stock exhaust manifolds have a fitting on each side where an line from the AIR system connects to. Also, on the passenger exhaust manifold, there is a fitting in which the EGR tube connects to. That is where those two systems come into play with aftermarket headers.

 

If i did need cats would i be able to put them on the pacesetter y pipe? Also is there any thing I will need to do after the headers are on?

 

Yes, they can be put into the y-pipe. You will need a cat smaller in length to get it to fit on the drivers side, but it is possible. After the headers are installed, unless you have locking header bolts, you are going to want to periodically run a wrench over the bolts to make sure they are all tight and haven't loosened at all.

 

o ok thanks and also what do I need to do to prevent an ses light?
