Frequently Asked Questions

Will this bolt directly to my existing exhaust?

Yes — it connects at factory slip-fit joints with no modifications. Test-fit before final tightening to confirm clearance at your vehicle's mounting brackets and underbody.

Do I need to replace the oxygen sensors?

Check your vehicle's service manual. Some V6 models require sensor replacement during converter swap; others reuse existing sensors. Have a shop or service manual confirm before you start.

What if the converter doesn't fit after I open it?

Contact us within 30 days of delivery with photos of the fitment issue. We'll verify the application match and work out next steps — no hassle.
