slant 6 exhaust manifold to pipe gasket???

[moparblood]

I hogged out the manifold for my 2 1/4 pipe, whats the best gasket that hopefully won't leak?
maybe double up. anyone know the # for perhaps mahle?
I've tried lock washers and sealer still leaks.
or whats a good gasket?

Remflex is the gold standard for exhaust gaskets. They are expensive but they really work.

Are you sure your manifold and head pipe are mating up properly? If one is off, twisted, at an angle, etc. it will make sealing very difficult.

Using a Remflex too - no leaks, and I have a turbo downstream of the exhaust manifold.

I use the Remflex gasket on mine and it's out to 2 1/2". No leaks at all.
