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 is made in the USA so as to control every step of the manufacturing process guaranteeing a superior product that you can rely upon. 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 has 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 Remflex 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.

have used these on quite a few SBF with headers. only gaskets ive ever used that have not leaked. even with high rpm offroading where the headers are glowing red and the exhaust is flexing alot i have never had them leak. when i take my headers off, i debate reusing them because they are usually still look fine.might need slightly longer bolts because they are thicker than standard gaskets

The first time I bought these, they came.... and I was shocked!! These products are made from a material I am already familiar with from my work. The material is called Grafoil and is used in the industrial valve industry, for the stem packing and end seals. 2000 psi rating on these valves... Remflex uses a screen material internally to hold the shape, but this material will conform to nearly any imperfection this side of hitting the header flange with a sledge hammer. I used them once when I had to remove my headers to drop the transmission, and they sealed so well, I bought another set and the collector gaskets when I ordered a new engine. I just installed the headers today and same results. The collector gaskets will be installed next weekend. I am sure they will seal up just like flange gaskets. I bought aluminum collector gaskets last time, and they were horrible. Leaked on literally 2/3rds of the entire surface.

First off I love these gaskets. The only thing is I wish you could save them. I bolted them up and had to unbolt my header about a month later. The gasket fell apart. But I still give it 5 stars because they seal up my Mac long tubes on my mustang which no other gaskets would do.

I would highly recommend these gaskets. I installed a custom set of headers on my car and burned through two sets of other gaskets after they developed leaks. Remflex was recommended by a local old school exhaust guy and once I installed them and torqued the header bolts, no leaks. I didn't even have to go back and re-tighten after getting the engine up to temp.

I changed to these gaskets after issues with OEM and standard replacements, and haven’t had an issue since. Install was easy, follow their directions. Very happy with the purchase.

Instantly solved a leaky header gasket on my 65 Mustang (with GT40P heads). Pricey but worth it.Update: Definitely not reusable, as the gasket sticks to the surface and gets destroyed when removing. Going to try copper next.

Seem nice. A little thick, pushed my headers out a bit. Assuming they seal and don't leak, they should be perfect.
