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

MagnaFlow direct-fit catalytic converters are designed for easy bolt-on installation for the professional installer. Welding, cutting, and tube-bending equipment are not required. These cats feature a ribbed body that minimizes expansion and distortion when the converters heat up. The ribs form a channel that protects the cushioning mat from direct exposure to exhaust gases, and they hold the ceramic catalyst in proper alignment. MagnaFlow converters use a monolithic honeycomb catalyst; the ceramic coating is designed for maximum flow and surface area, and the coating method is strictly controlled to maintain exact specifications. Improper coating could result in flow restrictions or an emissions test failure. These converters are designed to exact OE specifications and are available for the most popular vehicle makes and models.

Replacing your stock exhaust manifold and up-pipes should be the first step in building a high performance exhaust system. Pacific Performance Engineering exhaust manifolds are co-designed by Honeywell (Garrett) and PPE, using CAD software to maximize flow characteristics. The included up-pipe bellows are high-flow, internally sleeved, and manufactured from 11-gauge, 0.120 in. wall aircraft-grade stainless steel with a 2 in. O.D. The exhaust manifolds are machined from high-silicon moly cast iron; feature built-in bosses; and are pre-drilled and tapped for a 1/8 in. NPT EGT sensor. PPE exhaust manifolds will help lower exhaust gas temperatures, reduce drive pressure, and accelerate turbo spool-up while maintaining reliability. Order the model recommended for your application.

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.
