Shipping & Returns

Shipping

We currently ship within the United States only. Shipping is free on all orders, with tracked delivery.

Made to order

Every downpipe and sport catalyst is custom-made after you order — CNC-machined, TIG-welded and test-fitted before it leaves us. Because nothing sits on a shelf, please allow 10–14 business days for your order to be built and dispatched. You will receive tracking as soon as it ships.

Returns

Unused parts in original packaging can be returned within 30 days of delivery. As items are built to order, please double-check fitment before ordering — our team is happy to confirm compatibility for you first. Contact support@oktanperformance.com to arrange a return.
