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.

Rewarder Headers will not compromise performance, quality or fit to compete with inferior designs at cheap prices. Every Rewarder 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. Rewarder headers are carefully developed on the vehicles they are intended to fit and are re-checked numerous times during the design and manufacturing process.

Do all Rewarder headers have the same basic design?
No, absolutely not. Rewarder headers are designed and built to fit each applications specific requirements. The header's design is dependent on the intended vehicle usage and emissions requirements. Rewarder headers utilize five types of header designs:

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.
Manifold Replacement	4-tube stock manifold replacement headers are designed for easy installation and emissions compliance.
Shorty	4-tube shorty or “clippster” headers provide improved ground clearance for popular muscle cars and street rods.
Tight Tuck	4-tube tight tuck headers are the best solution for narrow frame rail street rods.

How important are flange and tubing thickness to header performance?
A properly machined and finished header flange eliminates annoying exhaust leaks which lead to horsepower loss. Rewarder headers utilize 3/8” flanges on passenger car and street rod applications. Thicker flanges hold up to heat better and are less likely to warp. Late model vehicles and high performance muscle cars produce super heated conditions that can warp “thinner” flanges.

Header tubing thickness and proper fixture welding techniques can affect the longevity of a header. Headers for light duty applications are built with 16 gauge tubing. Heavy-duty applications, such as motorhomes or tow vehicles demand thicker 14 gauge tubing. Rewarder headers are built in heavy duty jig fixtures which eliminate heat distortion and movement of the individual header tubes. Each header is welded using cyclical welding techniques which reduces tube distortion.

What finish is applied to a Rewarder header?
Metallic Ceramic Thermal Barrier Coating (Techline) is simply the best header finish on the market and comes standard on all Rewarder 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. 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. All coating in done in house.
