Lifetime Limited Warranty applies to Flowmaster stainless steel mufflers (excluding FlowFX series), all stainless steel exhaust systems (including FlowFX series), stainless steel pipes, air intake kits and oiled type filters (except cleaning kits), and other stainless steel exhaust accessories (except exhaust tips and racing products).
Three (3) Year Limited Warranty applies to Flowmaster aluminized steel mufflers, aluminized steel exhaust systems, aluminized steel pipes, exhaust tips and other non-race exhaust accessories.

Flowmaster, Inc. (“Flowmaster”) extends the following limited warranty to the original purchaser of its mufflers, exhaust systems, pipes, exhaust tips, headers and other non-race accessories (hereafter “products”), excluding catalytic converters sold under the Flowmaster brand. Flowmaster warrants the products mentioned above against defects in materials and workmanship for the period set forth below, when they are owned by the original purchaser and remain installed on the vehicle on which they were originally installed. This warranty is void if the product was not installed properly on the vehicle, was installed on a vehicle for which it was not designed, or was removed from the vehicle on which it was originally installed and reinstalled on another vehicle. This warranty shall not apply to normal wear, including interior/exterior sound levels, cosmetic issues such as coatings and material discoloration, any product that was installed on a racing vehicle, installed improperly or contrary to Flowmaster instructions, altered, misused, repaired, damaged from an accident, collision, undercarriage road impact or debris, or willful or negligent act. Note that all “straight-through” mufflers which use sound absorbing material inside the muffler to cancel sound…will degrade over time. This degradation of sound absorbing materials is considered “normal wear”…not a material defect.
The warranty set forth herein for Flowmaster stainless steel mufflers (except FlowFX), all stainless steel exhaust systems, stainless steel pipes, stainless steel exhaust accessories (except exhaust tips) and air intake kits and oiled type filters (except cleaning kits), extends for a period of the life of the original vehicle the product was installed on.

The warranty set forth herein for Flowmaster dry air intake filter elements extends for a period of two (2) years from the date of original purchase and the original vehicle it was installed on. The warranty set forth herein for Flowmaster Exhaust headers, FlowFX mufflers, and Delta Boost modules extends for a period of one (1) year from the date of original purchase and the original vehicle it was installed on. Header warranty does not cover damages caused by exhaust insulating wrap, and is void if the product was installed on a new or rebuilt engine during the initial break-in period.

The performance exhaust is an important part of your performance car. Flowmaster is one of the oldest and most respected and recognized names in aftermarket performance exhausts and one of the reasons LMPerformance carries Flowmaster American Thunder, and Flowmaster 40 Series Exhaust systems. For over thirty years Flowmaster has been one of the leaders in the design of specialty aftermarket exhaust parts. Flowmaster American Thunder & Flowmaster 40 series were first established to design and manufacture exhausts for racing in California. Flowmaster now produces performance exhaust systems, mufflers, and other products for a wide range of cars (including Mustangs, Camaros, Challengers, Corvettes, Chargers), trucks, SUV's, motorhomes and ATV'S. They create a line of high-performance "chambered" mufflers that is well known in the industry.
Flowmaster offers eleven diffferent series of mufflers that give top notch performance and great sound levels and tones. Flowmaster is especially noted for their Flowmaster 40 series muffler, with its original Flowmaster American Thunder sound and tone. If you're in the market for a Flowmaster 17106 Ford Mustang exhaust system- look no further!
