Ordered two sets today. $30.00 per set. Talked to one of the owners. Seemed like a nice guy. He said that they squish down from 1/8" to about 1/16", and work fine even if the flanges arnt perfectly flat. You DON'T need to over tighten them. 20 ft lbs is plenty. It's best to torque them as you'd torque a head gasket.
Hopefully this will be the end of burned through Felpros.
I hate to bring back old threads, but I stumbled across this and noticed no one has put up their experience!
These are the ONLY gaskets that I have gotten to work. I drove my we4 for 1.5 years with exhaust leaks and after trying the common gaskets, trying no gaskets and filing the header flange, I gave up!
I then learned about these gaskets, saw them on their site, and bought some from a local vender (he had to get them shipped).
They are very thick and pure layered graphite. To say that they crush and conform to the header is an UNDERSATEMENT! These things freakin' work so well I have taken to being a living advertisement for them! I even have them in my signiture!
One note: I think 20ft-lb is too much, I did that (or maybe 30, don't remember) and they overcrushed which caused the layers to seperate and squeeze out. I called the manufacturer (Remflex.com) and they said to try a bit less torque. Get this! He sent me out a new set free!!
CLIFFNOTES: Get them, hand torque them until they look compressed a bit. Reassemble and enjoy your extremely quiet little turbo monster!
