Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How do I check the manifold for leaks?

Start by tightening all clamp bolts to spec and then run the engine at low throttle while feeling for hot spots or escaping fumes around the joints. A light soapy water spray can also reveal leak points as bubbles will form.

Will the XRAY 681401 fit the stock NT18T without modification?

The part is designed for NT18T fitment. Most stock installations require no extra machining, but always verify alignment and sealing when installing on your chassis.

What maintenance does the manifold need?

Keep the exterior clean of oil and grime, check mounting hardware periodically for loosening, and inspect for cracks or wear after heavy running sessions.

Can I use other mufflers with this manifold?

The XRAY 681401 is optimised to work with the #681201 muffler. Other mufflers may fit but could require different sealing or adapters and may not deliver the same performance balance.
