Best Automotive Performance Exhaust System Gaskets

Remflex 1001 Exhaust Gasket for AMC V8 Engine, (Set of 2)
Remflex Exhaust Gaskets are good to 3000 degrees which far exceeds the temperature rating of any sealant. Heating and cooling of the exhaust system causes header and manifold flanges to warp resulting in gaps between the head and header which Remflex exhaust gaskets seal completely due to the thickness and compressibility of the 100 percent flexible graphite.
Reviews
"I have tried multiple times to get my headers to seal."
"worked great!"
"no more leaks, I use remflex on a few cars."
"Works perfectly as described no more leaks."
"This is the only gasket set that I know of that reliably seals my 360's exhaust manifolds."

"Finally someone is offering a gasket over the factory sealant...this gasket is high quality and fits perfectly...pay attention to the directions that come with it and it wont leak."
"I used sealant as suggested and it still doesn't enstill confidence I wish I had just used oem sealant. UPDATE: Back of the oil pan didn't seal up properly."

"Great part, dont forget to use rtv on the corners!"
"I look all around and the pan is right up against the oil filter housing, since the gasket is a 1/2” thick this gasket will not work and I’m going to have to silicone the whole pan and hope for the best."

"The blower bolts to the side of the stove near the rear and sucks the combustion gases out of the stove and sends them up the 3" chimney duct that I put inside the masonry chimney."
"The seal between the the ash tray and the body of the grill has a gasket, but there is some play. The Vision Grill ash tray has taken many forms in the last 5 years."
"I could have purchased new pre-cut gaskets from the stove manufacturer but the fact is every time I remove the draft inducer for maintenance the old gasket falls apart and can't be re-used without leaking smoke into the house."
"The only thing that could make this better would be if this company would offer pre-cut gaskets using this same material but customized for certain pellet stoves."
"working great ."
