Lifetime Warranty
The manufacturer warrants that all Magnaflow Performance products are
free from defects. Most of our mufflers* are warranted against blowouts
and defects in material and workmanship for as long as the original
purchaser owns the vehicle on which it was originally installed. The
warranty is void if the muffler is not installed properly on the vehicle
for which it is designed.
This warranty does not apply to
any muffler which has been installed on any commercial or racing vehicle
or which has been improperly installed, altered, or subjected to misuse
or damage from accidents. Also, cost of labor and any additional parts
required to complete installation of a replacement muffler are not
covered by this warranty.
The warranty
certificate, along with proof of purchase, MUST be presented to
the service outlet from which you originally purchased the muffler, or
any participating dealer, when making a claim for replacement. The
original muffler must also be returned and exchanged for a new muffler
of the same part number.
No other warranty, expressed or
implied (including merchantability), applies to the mufflers, nor is any
person or the manufacturer authorized to assume any other warranty. The
manufacturer does not assume any responsibility for any consequential
damages occasioned by the muffler, or inconvenience or interruption in
any operation.
This warranty gives you
specific legal rights, and you may also have other rights which vary
from state to state.

Converter Warranty Return
A
catalytic converter will rarely fail without a problem or malfunction
occurring somewhere in the emissions system upstream of the converter.
It is important to determine the cause of the failure and repair it, in
order to prevent a reoccurrence.
1. Carbon
Deposits
This is an example of a converter with carbon deposits in the ceramic
catalyst. This is usually a result of oil or antifreeze entering the
exhaust system or a too-rich fuel mixture. The heavy carbon deposit
clogs the converter and restricts exhaust flow.
2. Catalyst Fracture
This is an example of a catalyst fracture. The ceramic becomes loose,
then cracks and begins to break down. The pieces begin to obstruct flow,
creating backpressure and increasing the heat in the exhaust system.
3. Overheated or Running Hot
A converter glowing red-hot or displaying evidence of heat
discoloration, such as this one, is an indication of catalyst meltdown.
This is a serious condition that should be addressed immediately, as it
can cause additional damage to the engine.
4. Catalyst Meltdown
The catalyst pictured is the victim of meltdown, a condition occurring
from extremely high temperatures. The ceramic melts and collapses,
eliminating the honeycomb perforations and blocking exhaust flow, which
can cause additional damage to the engine. A variety of malfunctions,
including an incorrect fuel mixture, can create this condition. A
careful check and repair of the vehicle’s systems will help prevent a
reoccurrence.
5. OBDII Check Engine Light
All 1996 and later model passenger cars and light-duty trucks are
equipped with a second generation On-Board Diagnostics computer (OBD
II). This computer monitors the engine through various sensors to ensure
the emission control components are functioning properly. In case of a
malfunction of an emission component, a Malfunction Indicator Light
(MIL) will illuminate alerting the driver to possible problems.
Car Sound's Warranty Policy
The manufacturer
warrants that this catalytic converter is free from defects in materials
and workmanship. This catalytic converter has been designed and
manufactured to meet the Emission Performance requirements specified by
the Federal EPA and the California Air Resource Board (CARB). When the
vehicle is properly maintained, the catalytic converter is warranted to
meet such requirements from the date of installation for a mileage
duration which will vary from state to state; please check your specific
warranty card for exact details. The manufacturer further warrants the
catalytic converter’s external shell and end-pipes (those being attached
during the original manufacturing process and otherwise unaltered during
installation) against defects in materials and workmanship for 5 years
or 50,000 miles, whichever comes first, from date of installation.
The manufacturer’s
warranty is void and no liability can be assumed:
- If the catalytic converter
is not properly installed on the vehicle for which it is
designed and cataloged.
- If the catalytic converter
has been altered or repaired, or if it has been damaged by
negligence, accident or mishandling.
- If the catalytic converter
failure is related to the engine not operating within
original equipment specifications, to a vehicle with an
illegal add-on device or modified part, or to use of
specialty fuels, lubricants, sealants or additives.
The manufacturer
reserves the right to determine what constitutes the vehicle’s proper
operating condition. No other warranty, expressed or implied, including
merchantability, applies to the catalytic converter, nor is any person
or company authorized to assume any other warranty. The manufacturer
does not assume any responsibility for any consequential damages
occasioned by the catalytic converter, or inconvenience or interruption
in any operation. This warranty gives you specific legal rights. You may
also have other rights that vary from state to state.
