The picture you see is the same header with MCTBC which 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. It also provide corrosion resistance to protect it for years to come.

Please see our online catalog for specific application information.

Every Dougs 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. Dougs headers are carefully developed on the vehicles they are intended to fit and are re-checked numerous times during the design and manufacturing process.Every Dougs 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.
