UNSPSC 25173702: Mufflers or resonators

UNSPSC 25173702 Mufflers or resonators (Commodity) shows minimal recent purchasing activity directly aligned with the code's nominal scope. The source records include one bridge replacement project, one law enforcement equipment cooperative contract, one aftermarket vehicle parts master agreement, and several fleet maintenance and repair solicitations, none of which explicitly reference muffler or resonator procurement as a primary deliverable. The aftermarket vehicle parts contracts and bus/fleet repair parts solicitations tangentially cover exhaust and drivetrain components, but none designate mufflers or resonators as a line item, budget category, or material scope. State and local buyers soliciting under this code appear to embed muffler and resonator purchases within broader automotive parts and fleet maintenance agreements rather than conducting standalone procurements.

The geographic spread of recent activity spans Florida (Orange County bridge work, Brevard County fleet inventory, Sarasota County School Board parts agreement, Rockland County car wash), Texas (METRO transit bus exhaust parts, City of Atlanta heavy-duty trailers), Missouri (Rockwood School District bus parts), and Minnesota-Washington cooperative purchasing (Sourcewell). The one directly relevant recent opportunity is the Metropolitan Transit Authority of Harris County (METRO) IFB for exhaust parts for transit buses (IFBDOC2004895483), posted February 10, 2026, with bids due March 11, 2026, which explicitly solicits diesel particulate filters, oxygen sensors, temperature sensors, catalyst assemblies, and aftertreatment modules for Cummins, MCI, NABI, Nova, Orion, and New Flyer bus fleets—a firm fixed-price procurement requiring delivery within 30 calendar days to METRO's Central Supply Warehouse in Houston. The code activity is diffuse; state and local muffler and resonator demand typically flows through aftermarket parts supply agreements, fleet maintenance master contracts, and cooperative purchasing vehicles rather than category-specific RFPs.
