Important Notes:

FeltyFab titanium products are raw metal. Our titanium is not anodized or coated with any paint or oil. Hydrochloric acid will remove the natural finish from titanium. Please check your cleaners to ensure they are free of this acid. FeltyFab is not responsible for discolored titanium due to incorrect care or washing.

Aftermarket manifolds may have larger runners, leaving less room for aftermarket fasteners. Please double-check your manifold clearance prior to ordering.
