Ultimate Headers 321 Stainless Steel Headers

Ultimate Headers 321 Stainless Steel Headers integrate a cutting-edge, patented design, created specifically for maximum performance and minimal weight, with 3D-engineered flanges, and superior 321 stainless steel to deliver a unique combination of elegance and horsepower. Born in World War II for aircraft engine exhaust manifolds by adding titanium to basic nickel/chromium alloy steel, 321 stainless provides reduced weight, plus increased resistance to material fatigue and thermal cracking in high-heat environments. Finite Element Analysis (FEA) processes are used to create Ultimate Headers and the unique Ultimate Flanges with their signature, high-tech, ribbed reinforcements that reduce weight, improve flange cooling, and lessen heat-induced warpage; while providing the required clamping forces to eliminate leakage. Ultimate 321 Stainless Steel Headers' tight radius, investment-cast, 316L stainless steel elbows immediately turn the header tubes away from the exhaust ports with a radius smaller than the tube diameter (which can't be done using a tube bender); holding the header tubes close to the block—perfect for engine swaps. Investment casting also maintains the desired wall thickness and avoids the thinner sidewall created by tube bending at the point where exhaust gas temperature and volume are at their highest. These benefits, combined with the advanced Cometic MLS (multi-layer stainless steel) header gaskets included with each set of headers, give Ultimate Headers 321 Stainless Steel Headers the leading edge when it comes to adding a total performance-enhancing exhaust system. Features include: * Patented design * Includes premium corrosion and heat-resistant ARP 12-point, 300 grade stainless steel bolts and washers * Jig fixture, TIG-welded for precise quality control * Easy to install * Header tubes are mounted high and tight for a compact, space efficient package away from steering shafts and frame rails * Eye-catching flanges add dramatic improvement to the engine compartment * Available styles include rear-dump and block-hugger designs * Available in a variety of finishes, including mill, satin, mirror polish, ceramic coated silver, and ceramic coated black *Ultimate Headers Cast Header Flanges or Extreme Low-Profile Clamps (both sold separately) are recommended for the end of the collectors

Doug's Headers

Doug's Headers has long been recognized of as one of the premiere exhaust header manufacturers in the performance industry. Since1958, they have been producing high-quality, hand-built, mandrel-bent exhaust headers. Each and every header is tuned with the proper tube size and length to efficiently remove all of the exhaust from each cylinder, reducing pumping losses, and resulting in dramatic increases in horsepower and torque. Doug's headers are carefully developed on the vehicles that they are intended to fit and are re-checked numerous times during the design and manufacturing process. Their designs include mid-length headers, Tri-Y headers, and long tube headers, plus manifold replacement headers. Their headers come with all the necessary mounting hardware, collector reducers or connector pipes, premium extra-thick gaskets, and detailed installation instruction sheets. The gaskets are rated up to 1100 degrees F, pressures to 3700 psig (255 bar), and are designed for an exact port match with their headers. Doug's Headers offer a choice of finishes: * Metallic Ceramic Thermal Barrier Coating (MCTBC), which is polished with a vibratory finishing process that not only produces a high-luster aluminum appearance, but also compresses and activates the coating, which increases the surface hardness. The finish is 60 percent more corrosion resistant than an unpolished surface, easy to maintain, and will last for years under normal operation conditions. MCTBC also protects and extends the life of headers by creating a thermal barrier that significantly lowers under hood temperatures and protects the substrate metal from thermal fatigue. * Hi-Temp black coating is an affordably priced alternative to their MCTBC. This finish provides good corrosion and heat protection when compared to many of the "cheaper" header finishes being applied by our competitors. * Raw steel is available for individual customizing Unless otherwise noted, these headers are designed to fit the vehicle as it came from the manufacturer. This includes components like cylinder heads, chassis, steering, motor mounts, body mounts and bushings, etc. If your vehicle is using aftermarket components, parts from other applications, or custom altered parts, then it is the installer's responsibility to verify fitment.

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.
