There's not a lot round to protect. Make sure the PAS pipe isn't in the way, wrap it if you want. You may need to bend a touch the corners of the undertray.

Okay y'all.... help, please?

I bought a set of headers from protuninglab in October. They were cheap enough, and looked just like the cheap ones on Ebay.
I've wrapped 'em and silicone painted them, and finally ready to install.

Wrong.

They are wrong.

The collector flange is too small to bolt to the mid pipes. ::sigh::

So in researching a bit, it looks like the flange changed in 2000. Most of the headers I'm looking at on Ebay say they fit '97-'04, base and S, just like these do. But on closer inspection, I see slotted holes. It appears most are making them with the larger flange but slotting holes so they can be used on any 986.

But not mine.

I think I have a work around: I'll simply slot the holes of the mid-pipe flange. But here's the question:

I am assuming that the flanges are the only difference: that the header pipe diameter is the same on ALL of these cheap headers? So I'm not giving up anything by using these? (I'm not holding my breath that protuninglab is going to make me whole here)

Waddy'all know?

This is who I was going to suggest, I had always thought there were more differences too.

Ooohhhhh you're a gem!
Yeah, I used search, but it returned so many results, I read a sampling.... found nothing, tried again, ...... well.... you know the rest.

THANK YOU!

I should probably update so it's there later for someone;
They wouldn't take them back because i'd already wrapped and coated them. So I simply slotted the holes on the mid-pipe.... back in business.
