Ultimate Headers 5.0 Ford Coyote swap headers are designed to make installing a later generation engine into an earlier vehicle a much easier job … with great eye-appeal! Cast stainless steel flanges and the tight radius cast stainless steel elbows lets you put large tubes in tight places. The strength of 321 stainless steel tubes delivers a stronger, more durable header that is lighter than comparable header designs. Plus, you get a complete package with headers, header bolts, and a pair of matching Cometic HTS header gaskets.

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

Ultimate Headers extreme low-profile clamps offer an innovative solution for connecting exhaust system tubing where ground or body clearance is a problem. Cast from the same corrosion-resistant 316L alloy stainless steel as Ultimate's header and collector flanges, these connector flanges are engineered to stand up to the heat, stress, and vibration of high-performance engines. In addition, these low-profile clamps add a special level of elegance to any header/exhaust system installation. When clearance is an issue and strength is very important, Ultimate Headers extreme low-profile connector clamps deliver outstanding performance. Features include: * Allows up to a 13-degree offset for quick, easy installation * Uses a rugged, detachable, claw-style hinge * Increased ground clearance * Available for 2.5 or 3 in. tubing * Includes slip-in back-up mandrel to assure a leak-free, air-tight junction * Uses ARP hex head, 5/16 in. stainless steel bolt, washers, and nut to secure the joint * Available in two finishes: as-cast and mirror finish * Includes radiused flair tubing stubs
