About this item

  • 3-1/2" Pipe; Universal 3-1/2” Collector Flange, 3 Bolt Holes, 3-25/32" 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


Remflex Exhaust Gaskets are soft and compressible so the suggested torque for each gasket, which is generally much lower than factory torque, is listed on the back of each package. Remflex's unique flexible graphite material has been proven for more than 30 years in industrial applications, where temperatures routinely exceed 2000 degrees-day after day, week after week, year after year. For over 10 years Remflex have been bringing this technology to automotive enthusiasts of all kinds to eliminate exhaust leaks for good. Experience has shown that no gasket should be reused if you want a reliable seal, therefore Remflex do not sell or market gaskets as reusable even though it have been told that they have been reused successfully in the past. Do not use sealants of any type with gaskets. The sealant burns out rapidly leaving a gap which creates an exhaust leak. Remflex Exhaust Gaskets are good to 3000 degrees which far exceeds the temperature rating of any sealant.

These are the best header collector gaskets I’ve ever used. Have always sealed.

You can't buy a better exhaust gasket and I've used them all.

Broke right away installing them, never had 1 minute of run time. I’ve put hundreds of gaskets on over the years and this was a first for me

Great gaskets as long as Amazon doesn't ship them in a box with something large and damage them so you get to wait for new ones!

I read the promo from the advertiser and I tried the product. It worked to well that I bought a second set as a spare.
