Product Details

The Hooker Super Competition Long Tube Headers represent the pinnacle of exhaust header engineering, designed for racers and enthusiasts who demand maximum horsepower at the optimal point in the power curve. These headers feature 1.875-inch diameter primary tubes with a 30-inch length, paired with 3-inch collectors measuring 8 inches long, all finished in a durable metallic ceramic coating that provides superior heat resistance and protection.

Premium Construction:

  • Lightweight 18-gauge tubing provides excellent strength-to-weight ratio for racing applications
  • 5/16-inch machined flanges ensure a perfect, leak-free seal at the cylinder head
  • Mandrel-bent tubing maintains consistent diameter throughout for maximum exhaust flow
  • Industry-leading welds deliver exceptional durability under extreme racing conditions
  • Metallic ceramic coating reduces underhood temperatures while protecting against corrosion

Performance Engineering:

  • Tuned-length primary tubes maximize exhaust scavenging and gas velocity for increased power
  • Long transition collectors reduce backpressure and improve horsepower throughout the RPM range
  • Port-matched design matches the cylinder head port shape for optimal flow

All necessary installation hardware is included for a complete bolt-on installation. This product is legal for sale or use on Racing Use Only Vehicles and is not intended for street use. Breaking in an engine with ceramic coated headers will result in damage to the coating and will void all warranties—Hooker recommends using cast iron manifolds during engine break-in.

After reading several negative reviews, I was suspicious of the low price offered by Autoplicity but decided to try them out anyway. Much to my surprise, the belt for my car shipped immediately and arrived 2 days later via ground shipping from half way across the country. I was very pleasantly surprised with the speed of service and got my parts for the lowest price on the internet. A+!

They had the lowest price and great communication. Will order from them again thanks

Great service with the best prices I could find online. I will be ordering from them again!
