Will I need new hardware to install this, or does it use factory bolt points?

This system bolts to your existing catalytic converter and factory mounting points — you're reusing what's already there. Check that your mounting hardware is in good shape before install; if bolts are stripped or rusted, grab a new set.

Does the burnt tip need any prep or paint before I install it?

The tip arrives with the burnt finish already applied. No painting or prep work needed — bolt it on and you're done. The finish will deepen with heat cycles as you drive.

What's the return process if this doesn't fit right?

Contact ModSupply customer service with photos of the fit issue before cutting or permanently fastening anything. They'll walk you through next steps — keep your original packaging for potential returns.
