Ok

I have searched countless times and maybe im not getting the right keywords but if i can get these questions answered.


i have a 95Z

i got some stuff for it already not on yet though



I am investing into some hooker longtubes and apparently a Y-pipe


ok my questions are


Why do i need a new Y-pipe and what does it do (im a noob)
i know it goes 2-1 exhaust but what do i need a new one


what do i need for a complete header install

And since im gettin LT's i take it there goes my cats even though i want them


any help would be appreciated

you need a new Y pipe because the long tubes are just that... long. The factory Y pipe hooks to the manifolds up in the engine bay while the long tubes end back near the tranny crossmember. As far as the cats, you will lose them if you go with LTs unless you have a custom Y pipe made with cats.

Other things that you will need is Gasket and header bolts pretty much. Also if you plan on doing your headers you might as well go ahead and do plugs and wires along with it.

and dont forget o2 extenders...bolts for y pipe to header connections if there bolt together

Both have useful install pages with color pictures. That should answer all your questions.

Make sure to use a quality gasket and bolts. LOCKING bolts. You'll use a lot of PB Blaster too, or WD-40. If you are using an off road y-pipe, you'll need EGR block off plates and o2 sims. You don't need the sims, but you'll throw a code if you don't. I figured I would put the $40 for the sims toward my tune savings and just get it turned off then. You'll need zip ties too to keep your plug wires away from your headers. Some heat shielding tape won't hurt, either. And an LT4 knowck sensor. The headers are a lot louder, so your sensor might pick up some false knock and retard you timing.
