About Clamps, Flanges, Hangers & Hardware

Clamps, flanges, springs and hangers hold the exhaust to the engine and the frame. A cracked flange, a lost spring or a worn hanger lets the pipe rattle, leak or sag. The listings here are mostly for older two-stroke quads: a steel flange for the Honda ATC250R and TRX250R, hangers for the Yamaha Banshee, a pipe spring and O-ring kit, and a flange kit.

Match the part to the machine and the pipe. A flange has to match the pipe and the cylinder port, and a hanger has to line up with the frame mount. When a pipe comes off, replace the O-rings and springs that hold and seal its joints, since heat and vibration wear them out. Check what a kit includes before you order.

Brands in this category are FMF Racing and ModQuad. To finish the job, look at Exhaust Gaskets & Seals, Exhaust Pipes & Tips and Heat Shields & Wraps, all part of Exhaust & Emission Systems.

FAQs on exhaust clamps, flanges and hangers

What does an exhaust hanger do?

An exhaust hanger supports the pipe or muffler from the frame so its weight does not hang on the engine, and it limits vibration. A cracked or sagging one lets the pipe move and rattle, so replace it when it is worn.

Why does my exhaust pipe keep coming loose?

The usual causes are weak or stretched springs, hardened O-rings, a damaged flange or a worn hanger. Heat and vibration do the damage over time. Inspect each of them and replace what is worn, rather than just tightening.

Should I replace the O-rings when I remove the exhaust pipe?

Yes, that is good practice. O-rings and springs take heat and vibration, and old ones may no longer seal the joint. A kit that holds both is a simple way to refresh the connection when the pipe is off.

How do I choose the right exhaust flange?

Match your model and year, and the pipe it joins. The flange here is listed for the Honda ATC250R and TRX250R. A flange that does not fit the cylinder's exhaust port will leak, so check the listing.
