DC Sports Honda 3-Bolt Graphite Exhaust Gasket - 3" (RM-CB80)
This DC Sports exhaust gasket fixes one of the most annoying problems in any exhaust setup: flange leaks. It's a 3" Honda 3-bolt gasket built from multi-layer graphite with an integrated crush ring that bites down under load and holds a tight seal between your flanges. No mystery tech, just a properly built high-temp gasket that actually holds up.
The Crush Ring Is Why It Seals
If you've fought with ticking at idle, fumes sneaking into the cabin, or a gasket that won't stay sealed after a few heat cycles, the flange gasket is almost always the weak link. The integrated crush ring takes up the small gaps and imperfections you get on older or slightly warped flanges, which is exactly what you run into on a car that's been apart a few times. That's where a graphite gasket pulls ahead of the cheap paper stuff: it seals better, lasts longer, and doesn't crumble the first time you stress it with a hard pull.
Where It Fits
SKU RM-CB80 works on any 3" flange connection using the Honda three-bolt pattern. That covers cat-backs, mid-pipes, test pipes, high-flow cats, and track exhausts. It's a high-temp gasket you can run on a daily driver, a weekend car, or a track build without worrying about blowing it out a month later.
Worth the Extra Over Paper
A graphite gasket isn't as cheap as the thin paper gasket that comes in a generic kit. But those paper gaskets usually leak after a few heat cycles, especially on turbo cars or anything that sees real abuse, and then you're dropping your exhaust again to swap it. This one costs a bit more up front and saves you from doing the job twice. If you're already running a loud setup, you'll hear the difference when the flange actually seals.
