Cummins isn't much better. My price is still over $8 each. I get my sets for the shop from High Tech Turbo. Better price, plus it comes with new turbo bolts and a new turbo gasket.

Has anyone tried the High Tech exhaust gaskets?

For example FTE Diesel Multi Layer Steel (MLS) ?

I have always reused mine and have never had a problem just snug em down good and tight and maybe check them again after a heat cycle or 2.

I'm not wanting to drill my manifold because I have a second one that's already drilled...keep mine for good.

I reused mine

And you shouldnt have to pull the manifold to drill and tap for a pyro. Just unbolt the turbo, stick something in there to block it, and use a magnet to get most of the shavings out.

I've had my manifold off several times and have reused all mine. Don't seem to have any problems.

You don't even have to take the manifold or the turbo off to install a pyro. Just let the truck idle while you're drilling into the manifold and it should blow it out. Then just coat the tap in grease and the shavings will cling to it.
