Doug's Headers 2010 Catalog by Vic Hubbard Speed & Marine

A PerTronix Performance Brand

2010

We are excited to present our 2010 Catalog with fifteen new header designs ready to ship. Doug’s Headers, the most respected name in the header industry since the 60’s, began in 1958 as a small muffler shop in East Los Angeles, California. The company expanded rapidly into a shop that designed and built innovative headers for muscle cars and many of the sport’s top drag racers. Cars with the famous “Headers by Doug” decal were consistently among the fastest in their various classes. Doug Thorley, the company’s founder, had one philosophy, to build a header with the highest quality and best fit, which provides maximum engine performance output. After 52 years nothing has changed! Our PerTronix family of performance brands recently grew again with the addition of JBA Performance Exhaust. JBA has a 22 year tradition of building high quality stainless steel headers and exhaust systems with application emphasis on Late Model Trucks, SUV’s and Muscle Cars. Please see the inside back cover to familiarize yourself with our Ignition Products, Patriot Exhaust for Street Rods and Muscle Cars and Thunderbird Exhaust for the air-cooled Volkswagen market.

The PerTronix sponsored Duttweiler powered Hairston Motorsports and Racing 2007 GTO continues to impress the Pro-Street world by running the quickest ever elapsed time of 6.23 seconds at 231.30 MPH and recently set the national speed record of 230.23 MPH at the famous Famoso Raceway in Bakersfield, California during a West Coast Hot Rod event. Visit www.pertronix.com and follow the Team’s performance.

HEADER TECH 101 Thick flanges (3/8” to 5/8”)... no warping

Machined sealing surfaces... no annoying leaks

CNC mandrel bent tubes... accurate fit & better flow Precision formed long transition collectors... reduces backpressure TIG welded ports... added strength

Header tubes are pre-polished... better appearance

Heavy gauge tubing (16 & 14G)... longer life Polished MCTBC coating standard... corrosion and heat resistant up to 1400˚

How come there is such a price difference between header brands? Header development and design is complex and requires a substantial amount of time and resources to do the job right! Many manufacturers are unwilling to make the commitment and instead offer compromised headers at lower prices. Doug’s will not compromise performance, quality or fit to compete with inferior designs at cheap prices. Every Doug’s header is tuned with the proper tube size and length to efficiently remove all the exhaust from each cylinder, reducing pumping losses resulting in a dramatic increases in horsepower and torque. Doug’s headers are carefully developed on the vehicles they are intended to fit and are re-checked numerous times during the design and manufacturing process.

H E A D E R FA C T S What is included with a set of Doug’s headers? Every Doug’s header comes with all the necessary mounting hardware, collector reducers or connector pipes, premium gaskets and detailed installation instruction sheets. Our extra thick gaskets are rated up to 1100ºF, pressures to 3700 psig (255 bar), and are designed for an exact port match with Doug’s headers. We do not recommend the use of other aftermarket gaskets. Doug's premium gaskets are sold separately see pages 29-30 for applications. What finish is applied to a Doug’s headers? Metallic Ceramic Thermal Barrier Coating (MCTBC) is simply the best header finish on the market and comes standard on all Doug’s headers. MCTBC protects and extends the life of headers by creating a thermal barrier that significantly lowers underhood temperatures and protects the substrate metal from thermal fatigue. Prior to the application of coating, all header tubes are pre-polished to remove clamp marks and scratches that sometimes result from the mandrel tube bending process. After MCTBC is applied, it is polished with a vibratory finishing process that produces a high luster aluminum appearance. This coating is easy to maintain and will last for years under normal operating conditions. The polishing process compresses and activates the coating, which increases the surface hardness to produce a finish that is 60% more corrosion resistant than an unpolished surface. What should I do if I encounter an installation problem with my header? Header installation for the most part can be accomplished with simple hand tools, a floor jack and jack stands. Some applications can be very time consuming due to limited space in the engine compartment. Should you encounter a fitment problem do not attempt to modify or alter the header in any way or your warranty will become void. Call our knowledgeable technical staff for assistance at 909599-5955. Headers returned without prior written authorization will be refused. Read our complete warranty policy on the last page of this catalog.

ME H OA TD OE RR HO FA MC ETH SE A D E R S Do all Doug’s headers have the same basic design? No, absolutely not. Doug’s headers are designed for specific applications. The type of header design will change depending on the intended vehicle usage and emissions requirements. Doug’s headers for conventional V-8 applications utilize five types of header designs:

4-TUBE FULL LENGTH 4-tube full length headers are typically used for higher RPM horsepower, but can also increase the mid range torque in applications were there is room to fit a long tube design.

TRI-Y Tri-Y headers for muscle cars, trucks and motorhomes yield maximum power from off idle to 4500 RPM making them well suited for applications demanding maximum mid-range torque with maximum fuel economy.

4-TUBE MANIFOLD REPLACEMENT 4-tube stock manifold replacement headers are designed for easy installation and are emission control device compatible.

4-TUBE SHORTY 4-tube shorty or “clippster” headers provide improved ground clearance for popular muscle cars and street rods.

4-TUBE TIGHT TUCK 4-tube tight tuck headers are the best solution for narrow frame rail street rods.

Header application information is grouped into sections by vehicle type. The passenger car, street rod, 2WD truck, 4WD truck and motorhome headers are listed in their respective sections. Within each section applications are listed by vehicle make, model, engine family and year(s). Applications may have associated footnotes containing critical information. A footnote key can be found at the bottom of all odd numbered pages. Please make sure that you thoroughly read the footnotes prior to ordering. Some headers are available with more that one type of emissions provision. This requires a basic knowledge of the emission equipment found on the vehicle.
