Header Coatings...What do they do and do I have to get my MACs coated?
 

I am thinking of ordering MAC headers soon but I keep coming up with delimes or thing I didn't think about. I am going with the MAC Headers(93-95) and doing the slp s-pipe to do a single cat conversion. It would come out to about $600 with o2 sims, gaskets and shipping.

My car is a bolt on daily driver car and I plan on keeping it that way. I am going to keep my taylor wires on their as well.

What is the coating for?

My question is will this coating that comes with the MACs be sufficient?

For my car I was gonig to go w/the 94-95mac's, and the 94-95 catback, maybe the mac offroad pipe in between. Or maybe just get the 96' catback for now, and the mac's later and have it rigged at an exhasut shop.

What is the slp y pipe? will you send me a link?

My appoligies its a slp s-pipe which allows for the dual cat to single cat conversion to the 93-95 style exhaust.

the coating on the mac headers is an anti rusting coating on a n/a motor more than suffecient they get a little hot on forced indution why buy the slp y pipe when the mac headers come with a y-pipe makes everything bolt together and they have an off road pipe that makes things real easy for the price you are going to pay 600.00 will easily cover the mac headers and off roud pipe and o2 trickers

forgot to add in my prev.post if you are elliminating the cats you do not need the slp y-pipe just use the mac headers and there off road pipe 100% bolt on

Mac Headers = $430
Slp s-pipe = $50
O2 simms = $90
ORP(not sure= $90

Grand total = $680

I might go with the carsound hi-flow cat instead to keep the pitch from being raspy.

Speed inc. told me that do do the conversion to single cat I need the SLP S-pipe, keep in mind I have a hooker catback system already on my car for a dual cat setup.

yeah sorry it just looked in the mac catilog you are right did not know you had a cat back good luck as far as the coating you should be alright

Here's what I have to add.

I'm also looking at the MAC single cat headers. My setup will be like this:
'94-'95 MAC headers=>'94-'95 Y-pipe=>Bullet Muffler=>S-pipe=>'96-'97 style Cat-Back

Instead of getting O2 sims, I'm going to get the rear O2's programmed out by either pcmforless or madz28. At www.madz28.com you can get the O2's deleted plus get three other things programmed on your PCM for $75. That's way cheaper than the $90 O2 sims.

Also, the S-pipe does not go all the way from the '96-'97 catback to the Y-pipe. I think it still assumes that there will be a cat after the '94-'95 style Y-pipe. So you will still need something to fill the gap from the S-pipe to the Y-pipe. For me, that will either be a high flow cat or a bullet muffler.

Hope this helps.

Well I had talked to the owner of speed inc (Tom) and he told me that will be in place of the y-pipe and connect the header ends into the ORP which then would be followed by the catback.

All the S-pipe's I've seen connect the front of the cat-back to the rear of the single cat or ORP.
