Frequently Asked Questions

Will this bolt directly to my truck's exhaust?

Yes. This converter mounts at factory connection points — no welding, cutting, or exhaust piping rework needed. Hand-tighten at the clamp and flange, then torque to spec per your truck's service manual.

Does it come with gaskets or any mounting hardware?

The converter assembly ships as-is. You'll need new exhaust gaskets (typically available at any parts store) and may need fresh clamp bolts depending on your truck's age. Check what's reusable before installation.

What's the return process if it doesn't fit?

Test-fit before final tightening. If it's wrong for your vehicle, contact support within 30 days for a return or exchange — shipping may apply depending on your order terms.
