Do I need new exhaust gaskets and hardware when I install this?

Yes—always use fresh gaskets at the manifold and downstream flanges. Check your service manual for the correct bolt spec and torque value. Reusing old gaskets almost always causes leaks.

Can I install this myself with basic hand tools?

You'll need a jack, jack stands, basic wrenches, and a gasket scraper. The job is straightforward if you're comfortable working under the vehicle. If you've never done exhaust work, a shop install is safer and faster.

What's the return window if this doesn't fit or I change my mind?

Check ModSupply's standard return policy before purchase. Catalytic converters are core items—some retailers require the old unit back and may charge a restocking fee. Confirm the terms at checkout.
