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

Hedman 304 Stainless Steel Headers

Hedman 304 stainless steel headers offer your exhaust system 100 percent mandrel-bent, 16-gauge tubes and hefty 3/8 in. flanges constructed from 100 percent 304 stainless steel for superior heat and fatigue resistance. They are available ceramic coated or raw. The HTC and Black Maxx ceramic-metallic coatings offer superior heat insulation and anti-corrosion properties to protect your "Hedder" investment and retain more heat inside the header tubes for increased exhaust velocity and improved scavenging. Unless otherwise noted, these 304s 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.

Summit Racing™ Split Lock Bolt Kits

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.

FMF Racing MegaBomb Plus Header Pipes

FMF Racing's MegaBomb headers deliver more useable power and can lower noise levels by as much as 1.5dB. FMF Racing MegaBomb Plus header pipes provide all the awesome benefits of the originals, along with updated resonance chamber technology for better performance. The patented header design allows exhaust gasses to expand, cool, and ramp back up at a higher velocity, resulting in torque gains typically associated with longer headers and the healthy over-rev of a short header. When combined with an FMF Racing slip-on muffler, gains of up to 3 hp can be achieved with a stock motor. FMF MegaBomb Plus headers are best suited for Motocross, Supercross, and GNCC-style riding where more bottom to low end response is desired.
