Re: SLP Shorty Headers
Dyno Don is selling me one of his Y-Pipes with instructions on how to mate it to the SLPs.
How can yall tell they are stainless by pictures? Just curious.
And yea I know 409 has more iron in it than say 304.

Re: SLP Shorty Headers
How can you tell? I dunno. everything I've owned that was stainless ended up being a dull blackish like your pix. Everything I owned that was just cold rolled mild steel turned orangy and flaked.
Guess it's faith. The first 5 things I owned that I was told was stainless rusted a certain way.

Re: SLP Shorty Headers
Yeah, SLPs have just enuff carbon in them to discolor to black but they shouldn't rot in our lifetime.

Re: SLP Shorty Headers
So I am good to use steel headed brush drill bit to clean them up? It's going to obviously take off any of the coating left, but it looks like crap anyway.
After I get the entire headers to look like that little spot I did, what will they do? I'm going to have the headers in storage for probably a month before I use them, so should I do that or just leave them like they are for now? Basically would you clean them up if you had the free time or leave them like they are? If it has any negative effect I obviously don't want to do it.
Thanks for the info guys, makes me feel better about the purchase. Also is there not a single marking on the headers indicating what model they are?

Re: SLP Shorty Headers
Use a stainless steel wire brush to clean stainless headers or your just going to spread more carbon on them.
you can clean em up but they will turn back that way over time.

Re: SLP Shorty Headers
-tri-Y's
-shorties in 1 5/8"
-shorties in 1 3/4" which is what you have apparently. All SLP headers were stainless along with their y pipes to my knowledge.

Re: SLP Shorty Headers
Nope i dont think they marked them like hooker/edelbrock and others did. SLP had only three headers for our cars that im aware of
-tri-Y's
-shorties in 1 5/8"
-shorties in 1 3/4" which is what you have apparently. All SLP headers were stainless along with their y pipes to my knowledge.

As I finally just found out there are 2 typs of 1 5/8s headers.
The Tri-Y and the type that look like the 1 3/4 headers..

Re: SLP Shorty Headers
What if I use an abrasive head like this:
I'm not sure what they are made out of, but I do know they will take metal off easily if you aren't careful.
Anyone know if I can use this without spreading more carbon on the headers?

Re: SLP Shorty Headers
Take out the 3 bolts where this big plate thing on the column fastens to the firewall; a couple of seconds each elongating them about ¼" so that the base of the column could move over; put the screws back in; DONE. One of the easiest and most trivial parts of the installation, actually; took more effort than that just to re-route the plug wires. I certainly wouldn't put that in the class of "doesn't fit".

Re: SLP Shorty Headers
Old thread, I know. Can anyone provide a link to Eastwoods titanium ceramic coating? I searched Eastwood's site. Is it a spray paint, or powder coat?
