Warranty Disclaimer

Our 400-cell catted test pipes have been tested on dual-pulley setups; however, catalytic converters are considered a wear item and are not covered by warranty.

The warranty is void under the following conditions:

• Aggressive burble, crackle, anti-lag, or flame-producing tuning
• Two-step launch control or unburnt fuel detonation in the exhaust
• Sustained high-heat use such as drag racing or track driving
• Improper installation or physical damage

These conditions exceed normal operating limits and can lead to premature catalytic failure. For build-specific compatibility, please contact us prior to purchase.
