Hedman Street Headers

For the price, no other part can give you the horsepower and fuel economy improvements of Hedman headers. They make Hedman Street headers so well that they guarantee them to be free from defects--including cracks in the tubes and welds--for the life of the headers. Hedman Street headers are available uncoated or in Black Maxx or their polished HTC thermal ceramic coated finishes and, as an added bonus, they also come with all necessary gaskets and mounting hardware. 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. Special warning regarding Hedman painted headers only. The paint on these headers is not designed as a final finish; it is designed to protect the headers after the manufacturing process and during shipping. This paint will not withstand the high heat associated with engine break-in, nor will it withstand the heat cycles associated with any type of driving. It is recommended that this protective coating be stripped, and a high heat paint or coating designed for use on headers be applied.

MagnaFlow Direct-Fit Catalytic Converters

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.

Pypes Off-Road X-Pipes

Let your engine breathe easy! Pypes off-road X-pipes are free-flowing, with reinforcing plates at critical locations and are available in 409 stainless steel or polished 304 stainless steel for years of high-powered performance. Since V8s fire unevenly, exhaust exits in pulses, rather than in a steady flow. While one pipe is filled with pressure, the other pipe is relatively pressureless, but the connecting of the two pipes in a Siamese pattern allows pressure to be released to the other side. This action allows the exhaust to pass through the pipes quicker, and this improved "breathing" increases horsepower. Pypes X-pipes' high-quality, exceptionally versatile design and performance are a proven winner when it comes to bumping up the horsepower of your daily driver or race car. There's no skimping on materials here. All crossovers include dual 409 stainless reinforcement plates at the welds, where they are needed the most. All pipes are mandrel-bent, allowing for the maximum flow of exhaust gasses, which boosts acceleration. Fabricated using the highest quality materials, the smooth, seam-coated pipes resist corrosion and extend the life of your system.

Catco Direct-Fit Catalytic Converters

Since you have to use a catalytic converter anyhow, you might as well use one that will last a long time and maintain your vehicle's performance level in the process.

These Catco units are direct replacements for OE converters and will install with little or no modification. Some converters have steel air tubes with perforated holes to help distribute the airflow evenly, without robbing power. New flanges are included when necessary. Order the model designed for your vehicle application.
