Remflex GS16511 Gasket Sheet

This stuff is an absolute God-send! I've used it on several different exhaust applications. The first time was a cheap no-name SS header that wouldn't seal on the head side flanges or the downpipe flange. And this last time was an o2 sensor flange that had corroded away after 26yrs of service. Glad I saved my scraps from the first time, bc one cutout was perfect size for this o2 sensor flange gasket fix. I'm soooo glad I found some old hot rodders talking about this stuff in an online forum discussion! In 20+ years of car work I'd never heard of anyone mention it. Some guys talk about stacking laminated gaskets- and I have done that, but they always blow apart bc exhaust pressure eventually gets between the layers. Well it's been 3yrs and 14k hard miles on my cheap header setup (no flex pipe) and the material has held up beautifully, without blowouts. A warning - BE CAREFUL HANDLING AND CUTTING! This material is delicate af and WILL CRUMBLE if you bend it in the slightest! That said, it can crack a little and still seal just fine, if you get it in place and snug. But also, DON'T OVERTIGHTEN! It can squish out of your mating surfaces, since it's pure (soft) graphite without any mesh. I highly recommend buying a sheet to keep on hand, even if you don't need it immediately. Because that late night project might get stalled or completed, depending on whether you have a solution. It totally saved my a.ss finishing my truck exhaust at 3am and driving the next morning.

This high temp. gasket paper works great. All you need to cut it is a box cutting.

The best exhaust gasket material on the market. Very thick. Great crush

For close to 30 dollars I would expect the corners to be true and straight anyways. It's the best gasket material I know of so I'll probably end up ordering it again

Remflex is the be-all, end-all of gaskets. ESPECIALLY if you use other cheap exhaust parts, these gaskets are a must. A flat, metallic gasket only has so much compression in it to create a seal, a MLS gasket has less, but this gasket compresses and fills any gaps; so, when you buy a cheap exhaust that has warped flanges, don’t give the product a 1-Star because you were a cheapskate, buy a decent gasket and never fret.

Replaced the muffler on my truck and when i got done i had a leak at the flange connection. I bought a new gasket, put it on and it still leaked. Then i found this gasket material and it did the trick. I had no idea this stuff existed.

Bought this sheet of Remflex to make my own Gaskets for the Header to Cat Flange during a JBA Shorty Header Install. The provided JBA gaskets in their kit are thin and feel cheap so I used those as Templates for cutting on the Remflex Sheet. Used an exacto knife and did pretty well with extra left over for more gaskets in the future. For the Header to Block Connections, the Percy/Taylor ‘Seal for Good’ Gaskets are amazing, as well. 2002 Tundra V8 4.7L Engine with stock exhaust adding JBA Shorties. Its been a little over a year since and the gaskets are holding nicely. Do it!

Best exhaust gasket material available. Those claiming its " delicate" or not durable apparently cant read. Remflex makes it very clear not to bend. Solved my manifold gasket leaks quick and easy. No re torquing. Cut to shape of old gasket with razor blade, install, tighten bolts evenly until gasket is crushed about half its original thickness. DONE
