PRODUCT DETAILS
Honda Catalytic Converter Ring Gasket - Genuine OEM (18393-SH3-S00)
Hearing that annoying exhaust tick or rumble, especially on a cold start? Or cracking open an exhaust joint to install a header, a test pipe, or a new exhaust? Either way, you want a fresh one of these. This is the genuine Honda exhaust ring gasket, part 18393-SH3-S00, the donut-style gasket that seals your exhaust joint and keeps the fumes where they belong. It's a cheap little part that fixes a loud, leaky exhaust and, honestly, one you should never skip when you've got the joint apart.
Always Replace It When You Open The Joint
Here's the rule with these, and it'll save you a repeat job. This is a crush gasket, it seals by getting squished down tight when you torque the exhaust joint together, which means once it's been crushed, it's done. You can't reuse the old one and expect it to seal again, it'll just leak. So any time you unbolt that exhaust joint, for a header, an exhaust swap, a leak repair, whatever, you drop in a fresh gasket. Over the years the old one corrodes, crushes flat, or blows out, and that's what causes the ticking, hissing, and rumble of an exhaust leak, plus that exhaust smell you don't want. A couple bucks of fresh gasket seals it right back up.
Genuine Honda, Correct Size
This is the real Honda gasket, sized at 52.5mm to 53.5mm, so it fits the joint properly and seals clean. One thing worth checking: Honda uses more than one size of exhaust gasket, so make sure this 52.5-53.5mm size matches your joint before you order. For the huge list of cars below, this is the one. It's the same gasket Honda used from the factory, no guessing on fit.

Note: Genuine Honda exhaust ring gasket, part number 18393-SH3-S00, sized 52.5mm to 53.5mm. This donut-style crush gasket seals the exhaust joint; a worn, corroded, or crushed gasket causes an exhaust leak with ticking, hissing, or rumbling noise and exhaust odor. Because it seals by crushing, it should be replaced any time the exhaust joint is opened, such as during a header, test pipe, or exhaust installation, and should not be reused. Honda uses more than one exhaust gasket size, so confirm the 52.5-53.5mm size fits your joint before ordering. Fits the 1997-2003 Acura CL, 1986-2001 Acura Integra, 1986-1990 Acura Legend, 1991-2005 Acura NSX, 2002-2006 Acura RSX Base, 1995-2003 Acura TL, 1992-1994 Acura Vigor, 1980-2007 Honda Accord, 1980-2005 Honda Civic DX/EX/LX, 1999-2000 Honda Civic Si, 2002-2005 Honda Civic Si, 1997-2006 Honda CR-V, 1985-1991 Honda CRX, 1993-1997 Honda Del Sol S/Si/VTEC, 2007-2020 Honda Fit, 2000-2006 Honda Insight, 1995-2001 Honda Odyssey, and 1980-2001 Honda Prelude.
