How should I torque the manifold clamps?

Tighten clamps until the joint is sealed without overcompressing the mating faces. Check after a short run as thermal cycling can change torque values slightly.

Can I polish the manifold myself?

Light polishing can refresh the finish, but avoid aggressive abrasives that could alter mating surfaces or fitment dimensions.

Will using this manifold affect fuel consumption?

Changes to exhaust flow can slightly influence fuel use depending on tuning and driving style. Properly tuned engines are most efficient after fitting the manifold.

Is any break in procedure required?

Allow a few moderate runs and recheck all fasteners and seals. This helps ensure stable performance as components seat under heat cycles.

Does the manifold change exhaust tone?

Minor changes in exhaust tone are possible due to altered flow characteristics, especially when paired with different mufflers or tunings.
