CERAMIC COATING
Looking for a way to protect your turbo or exhaust manifold and improve its efficiency at the same time? Our in-house ceramic exhaust coating does both! Available in black or silver, these 2000+ degree ceramic coatings look great and provide an extra layer of protection against corrosion. By coating the exterior surfaces of your turbo hot side or manifold you retain the heat and energy in the exhaust, not in your engine bay. Improving under-hood temps and increasing efficiency with improved turbo spool are great reasons to add these coatings. Please note that ceramic coating is completed in-house and will add an additional lead time of 1-2 weeks to you order.
