Thick flanges (3/8" to 5/8")... no warping

CNC mandrel bent tubes... accurate fit & better flow

Precision formed long transition collectors... reduces backpressure

Heavy gauge tubing (16 & 14G)... longer life

Header tubes are pre-polished... better appearance

Doug's PASSENGER CAR HEADERS 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 increase 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.
