Manufacturer's Warranty — Flowmaster

Flowmaster warranty is tiered by material and product line. Lifetime Limited Warranty — stainless steel mufflers (FlowFX series excepted), all stainless steel exhaust systems (FlowFX included), stainless steel pipes, air intake kits and oiled-type filters (cleaning kits excepted), and other stainless steel exhaust accessories (exhaust tips and racing products excepted); this runs for the life of the original vehicle the part was installed on. Three (3) years — aluminized steel mufflers, exhaust systems and pipes, all exhaust tips, other non-race exhaust accessories, and commercial-vehicle applications of aluminized or stainless products. Two (2) years — Delta Force dry air intake filter elements. One (1) year — FlowFX series mufflers, Elite Series headers, and electronic components such as Delta Boost modules. Catalytic converters sold under the Flowmaster brand are excluded from this warranty. Coverage runs from the date of original purchase, to the original purchaser only, and only while the part remains on the vehicle it was originally installed on. Header coverage does not extend to damage caused by exhaust insulating wrap and is void if the header was fitted to a new or rebuilt engine during the initial break-in period. Sound-absorbing material inside “straight-through” mufflers degrades over time; Flowmaster treats that as normal wear, not a material defect. Also excluded: interior and exterior sound levels, cosmetic issues such as coatings and material discoloration, installation on a racing vehicle, improper installation or installation contrary to Flowmaster instructions, alteration, misuse, repair, accident, collision, undercarriage road impact or debris, and willful or negligent acts. To claim, the original purchaser returns the product either to the original retailer or directly to Flowmaster — a Returned Material Authorization (RMA) number must be obtained from Flowmaster first if returning to them — with proof of purchase showing place, price, product and date. Flowmaster's remedy is exchange for the same part number or refund of the purchase price at its option; installation, labor, towing and shipping costs are not covered.

Warranty terms are set by the manufacturer and may change. Full details and claims are handled directly by Flowmaster. Contact us if you need help with a warranty claim.
