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

Kooks Headers long tube headers are heavy-duty and crack-resistant, featuring large diameter stainless steel construction (most applications) with smooth-flowing mandrel-bent tubing. They include gaskets, bolts, and oxygen sensor extensions where required. Also available as kits with connection pipes, depending on the application, Kooks long tube header kits include individual connection pipes, a Y-pipe, X-pipe, or H-pipe to connect to the exhaust system. X-pipes are used primarily for high-rpm performance and race applications. H-pipes create lower end power and are used on street cars for increased performance with a comfortable sound level. These connection pipes are offered in three versions: * Off-road (non-catted) for full track use with no horsepower loss and the loudest exhaust tone * With high-flow catalytic converters; recommended for street driving with little or no horsepower loss and a deeper exhaust tone * With Kooks ultra-high performance GREENCATS catalytic converters; designed for naturally aspirated and forced induction engines up to 900 hp, eliminates most "Check Engine Light" warnings Note: Kooks Headers long tube headers and connection pipes may not be legal for sale, installation, or use in some areas.
