Your beautiful Cobra deserves the baddest exhaust system on the market. Engineered and constructed using 304 Stainless Steel and fabricated in the USA with precision cut, 3/8-inch warp-resistant and leak-free stainless-steel flanges. Each GAS-N header design has been rigorously tested to ensure it delivers the performance gains we promise and you'd expect.
Install the new 3” bolt pattern headers on your 351 Ford engines in less than an hour. With the 2” bolt pattern header it will take you longer because getting a wrench/fingers on the header bolts to tighten the bolts down can be frustrating. Please remember Ford design the 2” bolt pattern heads over 50 years ago and engine builders are still using them. If you have the option when building or rebuilding your engine ask for the 3” bolt pattern heads it will be more expensive but the fit and finish is outstanding.
Product features on this system includes:
- Primary sizes are available with 1-3/4" or 1-7/8"
- Header flange available with either 2" or 3" bolt pattern
- Will fit AFR with raised ports, Blueprint, Roush, Trick-flow, and Z heads
- Hand built and designed happily in the USA
