Pacesetter Headers are on! Read before you install.

[Tyler]

supposedly you have to soak the PCH gaskets before putting them on. then they work great.

SpeedyVY, Rob: I know of no set of headers that does not recommend the use of gaskets at the flange. Do you know what the flange is?

The Flange is the section of the header in which the primary tubes are welded to the matched exhaust ports for the cylinder head - mounts flush. You are trying to tell me that you don't need gaskets there? Are you aware that is where 90% of all exhaust leaks take place - is at the flange?

Yes you do need gaskets there. They are normally called headers gaskets, although that description is misleading.

You show me one set of headers that doesn't need flange gaskets and does not leak as a result.

At over 1600 degrees, I don't think RTV sealant is going to cut it.

Have you seen the collectors on the pacesetter headers? NO....the flange is a 2 or 3 bolt flat plate that is used to connect the headers to the y-pipe. This is where the exhaust leaks occured with RKSport headers. That is why people just had the y-pipe welded to the headers. Header gaskets are very necessary and don't tell people which to use because the best ones are the paper gaskets that came with the headers. The headers are a little different at the interface and will need a gasket that conforms better than the metal ones. That is all I have to rant about till someone pipes up about knowing something that they have never even seen or worked on.

What do u soak them in, just water or some other substance?

Water

You seem to mistake all metals for being strong unformable units? Copper and aluminum gaskets are the best thing you can use.

Paper will deteriorate after time. They will work, yes. But they are not the best. That is proven by those who care about performance and race - none of them use paper.

I never said anything about the collector being a 2 bolt or 3 bolt, I couldn't really give a @&*$*. What you had said was something about a "flange collector".

I asked you "Um what the hell is a flange collector???" and you never answered me.

The problem with RKSport headers for your info is not with the Y-Pipe to collectors. Its the fact that the flange is weak. It separates from the primaries and then causes them to leak - at the flange, until that flange is re-welded. I would never recommend welding your Y-Pipe to the headers at the collector, and is unneccesary as the only forseeable problem is really that the flange has separated from the primaries, and the headers themselves now are not supported in the manner in which they were designed to. This may cause them to leak in other places. Welding the other places where leaks occur will only re-inforce the problem to get worse.

Guys we have gone over this before....
The only place a gasket is needed is where the headers meet the block. They supply one. The flanges for the y-pipe are ball joints (search for my previous post for pics) they don't need a gasket. The fit like a ball in a glove, and are spring tensioned so they stay tight. You can weld this I suppose, but they need to have some flex. You will probably need to get the y-pipe welded to the cat though. [img]graemlins/thumbsup.gif[/img]

Exactly

If you want to continue using the stock and weak 2-bolt system you can. But me, I'd much rather use a stronger 3-bolt flange, and use gaskets.

Still didn't tell me what a flange collector was.

Pacesetters do not have a flange. The use a ball and socket connector. A flange collector is when there is a flange on the end of the header and one on the collector and you bolt the two flanges together with a collector gasket in between. Pacesetters don't have flanges...therefore no need for a collector gasket.
