Important Note on CELs & O2 Sensors
We’re designing this pipe with emissions behavior in mind, and we recommend running Xforce Mini Catalytic Converters in place of spacers to help reduce the chance of CELs or O2 sensor issues.

However, due to variances in tuning, climate, sensor condition, and individual vehicle response, we do not guarantee a CEL-free experience.
We are not responsible for failed inspections, O2 sensor misreadings, or emissions-related compliance issues. This part is intended for race use or off-road applications only..

These are performance parts—install at your own risk, and ideally, with a tune and solid prep.
_____
Disclaimer:
We are not responsible for emissions compliance, inspection results, or street legality. Catless units are intended for race vehicles and off-road use only.

Function Fabrication Warranty Policy

We stand behind our welds, always.

At Function Fabrication, every part is hand-built and thoroughly inspected before it leaves our shop. Because of that, we proudly offer the following warranty:

• Lifetime Warranty on Weld Failures & Manufacturing Defects
If a weld cracks under normal use—or a defect from the fabrication process causes a failure—we’ll repair or replace it at no cost to you.
This applies to the original owner only.

• 3-Year Coverage on Materials & Fitment
If a flange warps, a bung comes loose, or a pipe shifts out of spec due to workmanship within 3 years—we’ll make it right.
This does not include damage from extreme abuse, accidents, or modifications done after sale.

• What’s Not Covered:
• Normal wear & tear (e.g. discoloration, surface rust in non-stainless components)
• Damage from improper installation, tuning, or use outside intended purpose
• Catalytic converter damage caused by tuning, oil burn, or rich conditions
• Use of our race-only parts on street-driven or emissions-controlled vehicles
