just brought some SLP headers on the GP!! 30001C... now what do i need? do i have to buy the Installation kit AND the cat adapter?? that would be another $100!!!!! and i only thought i was saving money.. do the headers not even come with gaskets????

 

No gaskets or bolts, nothing... just steel. If you are having a shop install it I bet they could make a cat adapter pretty easy. The install kit has bolts (you have to reuse a couple of your old ones) header-head gaskets, header-y-pipe gaskets, and heat sleave for your plug wires. I was glad I bought the stuff (I did the z-racing GP and got a discount on the install stuff also) but I didn't have much time to go running back and forth to the store to find the right bolts. Good luck...

 

I also got the install kit through the Z-racing GP, and I'm glad I did. That's a lot of little stuff to nickle-and-dime you into the poorhouse. It was $85 in the GP (the 3" slipfit adapter and install kit together).

The kit also included (in addition to what BitchinCamaro listed): c-clamps, rubber tubing for the AIR connections, the plastic clamps and joints for the rubber tubing, a 90° elbow for the fan switch (not necessary, but if you ever need/want to change it, you'll be glad you installed it), y-pipe flange bolts, and an allen bolt for the dipstick tube. The fire sleeving isn't for the plug wires, it's for the sensor wires, and you don't reuse any bolts, just a couple studs (just givin you a hard time BC). The gaskets in the kit are good (haven't had any leakage problems), as well as the bolts (ARP 3/8th inch 12-point black oxide chromemolys).

 

Ooops... I forgot to mention mine was the w/o AIR kit, so that would explain why I didn't get that stuff. I didn't get that elbow for the fan switch though, which would have helped out a lot considering I destoryed the old switch and connector removing the old manifold.

 

So did I.

 

so do i get the $80 SLP installation kit.. or.


$11 for a set of 12 bolts (how many do i need)
$25 for upper gaskets
$11 collector gaskets
$11 wire protectors
---------
$58

i can get or have my own exhaust clamps..

I got 4 2" grade 8 3/8" -16 bolts for the collectors and the donut gaskets at local parts store, they're to some chevy trucks whatever, they fit, then a header bolt kit and a few 3/8-16 bolts for the ones that werent just flanged but had the tubes, appropriate length of course, and a set of mr gasket ultra seal flange gaskets.

 

how much did that cost you?? is it cheaper to buy everything seperate guys???

 

I dunno like 20-30 bux plus the cat adapter which was 30.

 

I also have the 30001c ... why does SLP require you to get a cat adaptor when the 30001 description states 'cat with air'. Would seem to me the Y pipe should be designed to fit right up to the Cat without an adaptor. But then they would miss out on collecting another $35.
I would assume if I am adding a Catco ... I also need the adaptor.

 

Unless you're running the headers open or open at the Y pipe, you need a cat adapter, its a 45* bend or so, and yes they should have just put the bend in the Y pipe but that would be easy now wouldnt it ?

 

thats another $35 or so.. plus $63 with the GP installation kit.

 

They did it that way because it would be cheaper than making three seperate Y-pipes for our cars' varying factory setups. Would you rather pay $35 for a seperate cat-adapter, or $125+ for a seperate y-pipe?
