While we are talking about aftermarket 'performance' parts that do absolutely nothing for performance but tend to lighten your wallet, let's not forget about aftermarket CAI kits. However, the primaries are not as long as full-length headers, so there’s increased clearance for lowered vehicles.
My engine 289 v8 from a 150 ford pick up This enhanced exhaust flow typically results in a broader torque curve than 4-1 headers.
Stock headers are fine for N/A mild bolt ons.
I want ceramic coated that will tie into the existing 2 1/2 exhaust. If any of the recommended tuners are in your area, use them.
What part of the country do you live in?
• We’ll keep our focus on the most common street performance designs: full-length, shorty, and mid-length.
Pingback: How to Choose an Aftermarket Exhaust System, i have a 2017 chevy camaro ss with a LT1 engine. A good set of headers will actually build up enough exhaust flow velocity to create energy pulses that pull or scavenge spent gases from the engine.
Of course, the first exhaust components to handle spent exhaust gases from your engine are the exhaust manifolds or headers. They provide longer primaries than the stock manifold to help produce more of that coveted low- and mid-range torque and power. Mild steel headers cost significantly less than varying types of stainless steel but don’t offer the durability of stainless steel.
This seems to go against all other information I’ve researched and is backward.
In that case save your money for the Procharger and screw long tubes.

The S197 airboxes flow enough air to easily support I think close to 500hp without restricting airflow. This is a 4spd car with a scatter sheild & large oil pan.. Hey Jim. Here’s a link to to the 13 parts that fit a ’67 Fairlane with the 427 engine.

For that reason, most header manufacturers recommend modest pipe diameters for street applications—1 ½-inch to 1 5/8-inch diameter primaries for a small block engine, for example. I need help with which headers to buy that will fit the car. Graph 1: Stock Exhaust Manifolds vs. Headers (Mast-headed 427 LSX) 18/19.
Shorty headers also typically work with the remaining stock exhaust components without modification (full-length headers require some modifications), so installation is often a quick, clean process.
I would like to see all your short & long tube headers offered for my 67 Ford Fairlane with FE 427 engine with 2″ and larger primaries.
With stock exhaust manifold? They are better able to stand up to extreme heat and will not rust.
Long tube headers make more top end power than shortys but sacrifice low and mid range. Put the manifolds back on and a new stainless system with the transverse muffler from a reputable fabricator, it sounds good, not deafening like before and the car is cooler in the summertime too.
I have stock headers, direct fit high flow catted x, and hooked it all up to the V6 dual exhaust conversion I already had.
That still leaves me with a couple old school problems to solve.
Headers are also available with a natural or painted finish. Plus, Sanderson headers provide excellent clearance around spark plugs, starter and chassis components, as well as ground clearance for lowered vehicles.
That means cooler, denser intake charges and increased horsepower. Completing the CAPTCHA proves you are a human and gives you temporary access to the web property.
Headers are installed because they boost the rate of exhaust flow out of your engine compared to OEM stock exhaust manifolds, which are typically designed to take up as little space as possible. Thanks. The superior thermal characteristics and rust-free surface of stainless steel allows them to maintain smooth, restriction-free exhaust flow throughout their lifespan.
As we mentioned earlier, full-length headers typically use a 4-1 design to empty the primaries into the collector pipe.
The result is a broader torque curve in the low- and mid-rpm range. Such is … There are many factors that go into choosing the right pipe diameter—engine size, horsepower, intended use of the vehicle, and more—but one common mistake that many hot rodders make is to assume bigger is better. In most cases, these four primary tubes empty into one collector pipe and form a “4-1” design.

Sorry for my noobness & thanks for your time!
Headers come in a variety of dimensions and configurations for specialty applications, including fenderwell, dragster, and circle track headers. https://www.summitracing.com/search/year/1967/make/ford/model/fairlane/part-type/headers/engine-size/7-0l-427/engine-family/ford-big-block-fe, What is the best header for an 1986 Honda Prelude Si 2.0L with PFI.

Made 404 to the wheels with a JLT intake and tune only.
The most common type of header coating is ceramic coating, which provides an added thermal barrier. Your email address will not be published.
But long tubes will make more power everywhere. If it's a Coyote 5.0, any aftermarket shorty will be a waste of money even on a forced induction set up. Shortys make more low and mid range power and torque. Another way to prevent getting this page in the future is to use Privacy Pass. As for shorty headers v stock manifolds, it depends on which platform you're starting from.
Tallahassee FL. Save my name, email, and website in this browser for the next time I comment. Trust me there is a big performance difference though they may look alike.
You said “shortys don’t make as much low and mid range power as long tube headers, but have the potential to produce higher RPM gains”. Discussion Starter • #1 • Aug 8, 2014. Your email address will not be published. In our “Exhaustive Research” post, we showed you how to choose the right exhaust system to help gain back lost horsepower. Cloudflare Ray ID: 5ec97a8e5b649754 The room is very limited looks like would have to cut Our friends at Summit Racing sell short and long-tube headers for your ’67 Fairlane. Full-length headers help produce more overall power with good power in the low- and mid-rpm ranges—right where most street-driven vehicles can use it the most! Both will help a stock engine, but if you mod things, they help more.
Shorty headers will help power over stock manifolds.
With help from a childhood friend that is a fantastic mechanic we will bring this 49 yr old machine into the 21st century. If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices.
I want the best headers to increase power, I have a 1970 Chevelle Malibu that I’m just beginning to make a motor swap to a ZZ6 engine.
The '11+ GT already has shorty headers from the factory so any aftermarket shorty header isn't likely to be much of an improvement. This set up leaves some issues to be resolved, such as custom made AC and power steering lines to mate up with existing stock parts. If it's a 3V, mid-length shorties such as the JBA yield a useful TQ gain over the stock manifolds especially at lower rpm on a N/A set up.
Mid-length headers offer some of the benefits of full-length and shorty headers. They provide longer primaries than the stock manifold to help produce more of that coveted low- and mid-range torque and power.
This project will take all winter and one thing my mechanic Dad taught me is take your time and do it right.
