Do I need a tune after installing this exhaust?

Stock ECU will run fine with a catback system. If you're pushing higher boost or running a front-mount intercooler, a tune optimizes fueling for the added flow, but it's not required for safe operation.

Will this bolt straight to my stock downpipe?

Yes, catback systems mount at the turbo outlet. No custom fabrication needed. Confirm all gasket surfaces are clean before final assembly.

Does this come with mounting hardware and clamps?

Mounting hardware is not confirmed in the product listing. Before installation, verify all clamp sizes and fasteners against your vehicle's service manual or contact our team for a complete hardware checklist.
