According to Don, "the shorty header isn't going to be a limiting factor in RPM - especially on a late-model, catalytic converter equipped street vehicle. Engine design, cam specs, cylinder heads, intake, and the cats themselves are all going to affect the RPM range before the shorty header hurts performance.".

Otherwise, long-tube headers are generally considered to be the best for reducing back pressure as much as possible, and therefore the best for scavenging — this is despite the fact that they actually technically flow less than shorty headers generally do, but after the section above, we have a good understanding of why that is.

Shorty Headers. Shorty headers are perhaps inappropriately named, because they're really only short vs long tube headers. Compared to your stock exhaust manifold, shorty headers still have a much longer tube. Because of how shorty headers are shaped though, you should still be able to use all of the other components of your exhaust, which

Performance. Shorty headers can improve the performance of your car by increasing exhaust flow and reducing back pressure. This can lead to more power and better fuel efficiency. Shorty headers are also known for providing better low- to mid-range torque, making them a popular choice for daily drivers.

Long-Tube Headers. Long-tube headers make their power in the mid- to high-RPM range and are superior to both stock and most aftermarket shorty headers. If you can get long-tube headers to fit, you'll usually realize the most power gains. And that part about fitment is no small thing.

Cost of Long Tube Vs Shorty Headers. The cost of headers depends mainly on the fabrication quality, complexity, and materials it is made of. Based on this, short tube headers tend to be more expensive as they require lots of fabrications. Therefore, the price range for a short tube range between $370 to $600.

1. Header Size: Bigger Isn't Always Better. One of the main considerations in choosing a set of headers is the diameter of the primaries, which are the pipes that connect directly to the exhaust ports. There are many factors that go into choosing the right pipe diameter—engine size, horsepower, intended use of the vehicle, and more—but

Shorty style headers were quite popular back with Fox body owners as much as power was left on the table by not going with a full length. The difference here is that FRPP wished to obtain a CARB exemption and that simply wasn't going to happen if the cats were removed. So two numbers came forth, M-9430-C54 (uncoated stainless) and M-9430-C54C

INSTALLING SHORTY HEADERS VS INSTALLING LONG TUBE HEADERS. Installing Shorty is a great project that you can do in as little as an hour. The first step is to disconnect the car battery and lift your vehicle. Once this is done, all you need to do is loosen the mid-pipe from the existing exhaust manifold and gently connect the headers.

Shorty headers are characterized by their shorter primary tubes, which are typically only 1-1.5 feet in length. This design allows for a quicker airflow, resulting in a sharper, more crisp sound. Shorty headers tend to produce a more aggressive and throaty exhaust note that is loud and attention-grabbing.

For example, for a 350ci engine with a peak torque goal of 5,000 rpm: PPA = (5,000 88,200) 43.75 ci. PPA = 2.48. To see what the theoretical peak torque rpm of a certain set of headers is for your

https://carperformanceboss.com/long-vs-short-tube-headers-horsepower/
Long tube headers provide horsepower on higher RPM scale, whereas short tube headers on lower RPM scale. Long tube headers work the best at the peak of the RPM scale. When the engine reaches the red line of its RPM, this is where long tube headers deliver the most out of it. This is most suitable for drag racing applications where the peak

What Are Shorty Headers? Most enthusiasts know that the factory exhaust manifold can be extremely restrictive to gaining more horsepower and torque. What a shorty header will do, is allow for a greater diameter runner to allow for more exhaust gases to run efficiently. Shorty headers will solve the problem that most stock manifolds can not.

Maybe 5 years ago, a chevy magazine did a write up where they compared 7 or 8 headers including shorties, block huggers, log manifolds, and full length. the shorties and block huggers split the difference between the the full length and log type manifolds. However, the cam was fairly big (compcam 292H).

The engine is already cammed and with some shorty headers and hot air intake. I can't drive it on the street because the brakes are shit and I don't want to die trying to street tune it until he fixes them. Onto my problem. I got it idling ok for the most part and in closed loop fuel trims are decent and idle is around the 850 commanded.
