It is recommended that this protective coating be stripped, and a high heat paint or coating designed for use on headers be applied.

MagnaFlow Universal Catalytic Converters

MagnaFlow universal catalytic converters by Car Sound form the basic building blocks for many applications. The main benefit of universal catalytic converters is that one unit may cover a wide variety of vehicle makes and models. Installing universal converters often requires the use of welding, cutting, and tube-bending equipment that is readily available to most professional installers. They are extremely well made, with features such as: * A ribbed body that minimizes expansion and distortion when the converter heats up. They form a channel that protects the cushioning mat from direct exposure to exhaust gasses, and hold the ceramic catalyst in proper alignment. * A 1/2 in. lap joint where the necks meet the body. The neck does not extend into the converter body, where it could hamper exhaust flow. * Manufactured with separate dies on different sized inlets. Putting larger neck sizes on smaller bodies would reduce the flow of the converter and the quality of the product. * A monolithic honeycomb catalyst. The ceramic is designed for maximum flow and surface area. The coating method is strictly controlled to maintain exact specifications. * Seam-welded close to the converter body for a strong, tight bond. Welding along the edge could allow the converter to expand like the folds in an accordion, allowing the catalyst to move around. * Heavier-gauge stainless steel, tip-to-tip. They do not use inferior mixed weights and materials. * An aluminized or stainless OEM-style ribbed heat shield that creates a rigid wall of protection against heat and adds to the structural stability of the converter.

Mr. Gasket Header Bolts

Installing headers can sometimes be a real pain, due to the tight spaces and the location and shape of the tubes. Mr. Gasket can help make installation a little easier and also help prevent annoying exhaust leaks from under-tightened header bolts. They have both the socket-head and hex-head styles of header bolts available. Hex types are heat-treated Grade 5 steel and have smaller-than-standard heads to ease access in tight spaces. Socket-head bolts are made from stronger Grade 8 steel for added ruggedness and they're great for those really difficult-to-reach spots. Both styles have a protective black oxide finish.
