Does this need to connect to my factory downpipe?

Yes — this is a catback system, so it bolts directly to your existing downpipe at the catalytic converter outlet. No downpipe modification or replacement required.

Will I need new gaskets or seals when I install this?

Check your vehicle's service manual for recommended gasket specs at the catback connection point. Most installations reuse factory gaskets, but fresh seals are cheap insurance against leaks.

Can I paint or coat the exterior?

Stainless steel can be ceramic coated or painted if you want custom color, but it doesn't require it — the material won't rust bare. Light polishing keeps it looking stock or showroom-fresh.
