Parts for your 2017 Honda Odyssey-Exhaust gasket

2017 Honda Odyssey exhaust gasket: what it does and when to replace it

Yes, the 2017 Honda Odyssey is built with multiple exhaust gaskets. This is confirmed by Honda’s Service Manual for the 2014–2017 Odyssey (Exhaust System and Engine/Exhaust Manifold sections) and the Honda Electronic Parts Catalogue, which list exhaust manifold gaskets, a front pipe “donut” gasket, and rear/mid-pipe flange gaskets. Trade databases used by workshops across Australia and New Zealand (such as ALLDATA/Mitchell 1) show the same gasket positions and replacement procedures.

The purpose of an exhaust gasket is simple but critical: it seals the joints where exhaust components bolt together so spent gases can’t leak out under the bonnet or beneath the cabin. On a 2017 Odyssey, that means keeping the seal tight at the cylinder head to manifold, at the catalytic converter/front pipe junction, and at one or more flanges further down the system. Good sealing stops hissy or ticking noises on cold start, prevents exhaust odour making its way into the cabin, protects nearby components from heat and soot, and helps the oxygen sensors read accurately for proper fuel control.

• Front pipe/catalytic converter donut gasket
• Muffler and mid-pipe flange gaskets

As part of servicing of a 2017-honda-odyssey exhaust-gasket, the workshop will usually replace any gasket that’s been disturbed. These parts aren’t a routine, kilometre-based item
