Frequently Asked Questions

How many genuine Honda muffler connecting tubes are included?

One rubber connecting tube, Honda OEM 18473-323-000, is included. The original four-muffler system uses several connector rubbers, and not every position uses this same OEM number, so match the joint position before ordering multiples.

When should muffler connecting tube 18473-323-000 be replaced?

Replace it if the rubber is split, hardened, swollen or no longer seals the exhaust joint. Also inspect the mating pipes and clamps because a new tube cannot seal badly corroded or distorted metal.

Can sealant compensate for the wrong connector tube?

No. Match Honda OEM 18473-323-000, pipe diameters and joint position. Use only the assembly method specified for the exhaust system.
