Hooker Headers 6901HKR Details

Hooker Competition headers offer the best value in the high performance header market. Designed for the value-conscious buyer who is running either a "stock" or "mildly-modified" engine, Hooker Competition headers offer premium features at a very competitive price. Made of durable 16 gauge mild steel tubing, the Hooker Competition header design utilizes a long transition collector to reduce back pressure and increase exhaust flow. A perfect sealing surface is assured with the 5/16" machined flanges, with welded O-ring seals. Experience has proven that this flange size is ideal to maintain header integrity and be pliable enough to seal each exhaust port. Tubing is mandrel-bent to maintain metal strength and provide consistent tube diameter at radii to maximize performance.

  • Tuned-length primary tubes for street performance
  • Mandrel-bent tubing for smooth exhaust flow
  • Light weight & sturdy 16-gauge tubing
  • Long transition collector for decreased back pressure
  • 5/16 machined flanges with sealing rings for a perfect seal
  • Industry™s best welds for durability
  • Designed for easy, trouble-free fit
  • All necessary hardware included for a complete installation
  • Header works with C6 transmissions
  • Power Steering bracket 10961HKR required for vehicles with power streering
  • Works with power brakes, air conditioning, automatic and manual transmissions

Overall Assessment

Customers praised the product for its precise fit and excellent finish, noting that it was particularly suitable for cars with a C6 transmission. The ease of installation was routinely lauded, and the sound quality after installation was deemed superior. Users were satisfied enough to consider repurchasing for other vehicles. Some customers, however, were disappointed by the lack of certain components in the package. Despite this, the product stood out for its quality, functionality, and fit. Most customers would recommend it over competitors.

Supposedly this would fit my 351w with gt40p heads, not the case. I had to cut and rework entire left side and do work on two cylinder ports on right side. Half the bolts would'nt fit in their holes due to lack of clearence, even with the headers on the work bench

They fit exactly as the manufacturer advertised, they even worked with a column shifter. The manufacturer said they wouldn't. I can't be any more pleased. This was the only header I have found that fit this car.

These were purchased for my 351W 1969 Mustang. Great price and just what I was looking for. I have a 351W Ford Ranchero and will likely purchase a set for that also.
