Frequently Asked Questions
Will this bolt straight onto my exhaust without welding?
Yes. This converter uses factory flange connections—slides into place and bolts to your existing exhaust piping. No cutting or welding needed.
Do I need to do anything to the old exhaust pipes before installing this?
Inspect the flanges for corrosion or damage. Clean them if needed so the new unit seats flush. If flanges are cracked or severely rusted, address those first to ensure a solid seal.
What if the converter doesn't fit or I need to return it?
Test-fit before you commit to tightening everything down. If there's a clearance issue or it's not what you expected, contact ModSupply within the return window—we handle the logistics from there.
