Universal 3” Collector Flange, 3 Bolt Holes, 3-3/8" Bolt Hole Spacing, 2/Set.
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.
Remflex exhaust gaskets come in a standard 1/8 inch thickness and are designed to crush 50 percent allowing them to fill any pits or gaps in the flange surface up to 1/16 inch.
The aluminum cylinder head and steel header or manifold combination are configurations that readily cause gap issues in the mating flanges due to contraction and expansion of the dissimilar materials.
Remflex exhaust gaskets fill those gaps permanently.
There are no rubber binders or composite materials in Remflex exhaust gaskets so they will not shrink or harden due to time or temperature eliminating the need to go back and continually retighten your flange bolts.

Universal 2-1/2” Collector Flange, 3 Bolt Holes, 3-1/32" Bolt Hole Spacing, 2/Set.

Dynatech header flanges are of the highest quality for a great start to your exhaust header.
1/4 thick and CNC laser cut for a clean transition from the cylinder head port to the header tube.
This is made of mild steel for a strong long-lasting construction.
A great exhaust system starts at the beginning - the flange and gaskets.
A big Dynatech advantage is the wide selection of port matched flanges.
