XRAY 681401 NT18T Racing Manifold  [XR-681401]

Maximise NT18T Exhaust Flow with XRAY 681401

Designed for hobbyists chasing cleaner power delivery, the XRAY 681401 manifold refines the flow path on the NT18T engine to tighten throttle feel. Using the matching #681201 muffler completes the tuned exhaust stack.

Material and Finish Details

The XRAY 681401 is made from polished aluminum, offering both a neat appearance and resistance to heat during extended running. The choice of material supports repeated use in demanding race conditions.

Why It Helps on Track

With flow-smoothed internals, the manifold reduces chaotic exhaust pulses and promotes stronger midrange and top end for the NT18T. The result is improved acceleration out of corners and more consistent lap times.

Installation Notes for Tuners

Ensure the manifold seats properly against the NT18T and the #681201 muffler, checking for any misalignment. Recheck clamps after a few runs and use quality fuel and a tuned carb to unlock the manifold benefits.

For competitive NT18T builds the XRAY 681401 offers a durable, flow-optimised option that complements a tuned nitro setup.
