Stage 8's Grade 8 locking header fasteners use a patented system that consists of a grooved hex-head bolt or nut, a retainer, and a snap clip. The retainer fits over the bolt head and locks the bolt against the header tube, and the snap clip holds the retainer in place. Once Stage 8 header fasteners are tightened down, they won't back out, eliminating leakage and blown header gaskets from loose bolts.

Summit Racing™ split lock bolt kits put a new twist on the theory of mechanical locking fasteners. These innovative bolts use a locking set pin built into the bolt itself—and when tightened, the set pin expands the bolt threads against the thread wall. This, in turn, provides a locking system without having to use any additional wires, locking compounds, or lock washers. To remove the split lock bolts, simply loosen the set pin and back out the fastener. They are available in a variety of thread sizes, for engine applications from the 1950s and up.

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.

The matching self-locking flange nuts are available in both hex-head and 12-point styles. For corrosion protection, the studs have a black oxide finish, while the nuts are brightly zinc plated.

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.
