INSTALLATION MANUAL
Lifetime Warranty
MagnaFlow warrants that all MagnaFlow Performance products are free from defects. Most MagnaFlow 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.
*MagnaFlow's XL Series muffler/exhaust, catalytic converter, and titanium exhaust line carries a Limited Warranty.
