Aftermarket performance parts can affect your factory warranty on related components under the Magnuson-Moss Warranty Act — a dealer must prove the part caused the failure to deny a claim. We recommend speaking with your dealer or tuner. Our parts are precision-engineered to factory tolerances and we stand behind every product with our own Lifetime Warranty against defects and fitment issues.

Some parts — particularly downpipes, intake kits, and fuel system upgrades — will require or strongly benefit from an ECU tune to see full performance gains and to prevent check engine lights. Parts like heat exchangers, oil coolers, and hardware do not require a tune. We recommend reaching out to us or your local tuner before purchasing if you're unsure.

We accept returns within 30 days of delivery on unused, uninstalled, and undamaged items in original packaging. Custom or made-to-order parts are non-returnable. To start a return, contact us at rvngperformance@yahoo.com with your order number. Return shipping is the customer's responsibility unless the item arrived damaged or incorrect.

Catless downpipes are intended for off-road and track use only. They are not emissions compliant and will trigger a check engine light without an appropriate tune or O2 spacers. If you need a street-legal option, contact us — we can discuss catted alternatives depending on your platform.

Every RVNG product is developed and validated on the specific platforms listed. If your exact build year, model, or configuration isn't listed, contact us before ordering — we'll confirm fitment. We stand behind every part with our Fitment Guarantee: if it doesn't fit as described, we'll make it right.
