Parts for your 2011 Honda Elysion-Exhaust gasket

2011 Honda Elysion exhaust gasket — what it does and when to replace it

Yes, the 2011 Honda Elysion uses exhaust gaskets. Honda’s service information and the Honda electronic parts catalogue (EPC) for Elysion chassis codes RR1–RR5 list multiple exhaust gaskets, including the exhaust manifold-to-cylinder head gasket, a donut/collector gasket for the spring-bolt joint, and flat flange gaskets further down the system. These appear in the factory workshop manual’s Exhaust System section and in OEM parts diagrams labelled as “GASKET, EX. MANIFOLD” and “GASKET, EX. PIPE,” covering both K24A four-cylinder and J-series V6 variants.

On this model, the exhaust gasket’s job is to seal the hot gas path so nothing escapes before it reaches the catalytic converter and mufflers. A good seal keeps the cabin quiet, protects sensors from false readings, and helps the engine run efficiently. Up front you’ll find the manifold gasket, then a spring-loaded joint with a crush-style donut gasket, and further back, flat gaskets at flanges near the centre pipe and rear muffler.

There’s no fixed service interval for exhaust gaskets on a 2011 Elysion — they’re replaced when disturbed or when a leak shows up. Common clues are a ticking noise on cold start that softens as the metal heats, a whiff of exhaust near the engine bay, soot marks around a joint, or lean/efficiency codes from the O2 sensors. If the exhaust has been off for other work (cat, O2 sensors, engine mounts, gearbox), budget for new gaskets, reusing old ones often leads to weeps or a comeback.

When fitting, lightly clean the mating faces, check flanges for warping, and torque the fasteners to spec in a cross pattern. For the spring-bolt donut, ensure the gasket sits square and the springs are evenly tensioned. Use quality OEM or reputable aftermarket gaskets, avoid exhaust paste ahead of the catalytic converter. A dab of high-temp anti-seize on studs/nuts is fine, but keep it off O2 sensors. After a few heat cycles, it’s good practice to recheck accessible fasteners.

If there’s any hint of fumes in the cabin, don’t drive it — aside from safety, an exhaust leak upstream of the cat can skew sensor readings and upset fuel trims. In Australia and New Zealand, visible leaks or excessive noise can also attract a failed roadworthy/WOF, so it’s worth sorting promptly.

• Typical gasket locations on 2011 Elysion: manifold-to-head, manifold/collector donut, centre-pipe flange, rear muffler flange.
• Replace whenever the joint is separated or when leakage/noise is detected.
• Use new hardware if studs, springs, or nuts are corroded.

Popular questions about 2011 Honda Elysion exhaust gaskets

Does the 2011 Honda Elysion actually have exhaust gaskets?

It does. Honda’s workshop manual and EPC for RR1–RR5 show a manifold gasket, a donut gasket at the spring-bolt joint, and additional flange gaskets further downstream. Both K24A and J-series V6 models use them.

What are the signs an exhaust gasket is failing on an Elysion?

A sharp ticking on cold start that quietens when warm, a sooty stain at a joint, exhaust smell near the engine bay or under the cabin, and fuel trim/O2-related fault codes are the usual giveaways. You might also hear a chuffing noise under load.

Should gaskets be replaced any time the exhaust is removed?

Yes — on these Hondas, once crushed, the gaskets rarely reseal perfectly. Fit new gaskets and, if needed, new spring bolts and nuts. Clean mating faces and torque to spec to avoid leaks and sensor issues.
