What is an equal length header?
The equal length header is characterized by having all runners be the same length, hence the name. That means the exhaust gasses travel the same distance before they merge into the collector.
Do equal length headers require a tune?
yes, you will need a tune. for any engine modification that is not a catback, retune/adjust the tune in the car.
Do you need a tune for Catless headers?
If you are planning on getting a catless header then yes you will need a tune. You do not need a tune with any header. Getting a CEL for cat efficiency will not do anything other than cause you to fail emissions.
Do exhaust pipes need to be the same length?
Bottom line, yes, the pipes should be the same length. Here is whatthe article says: “Assuming that an exhaust system is otherwise properly designed, equal length pipes offer some benefits that are not present with unequal length pipes.
Do I need a tune for unequal length headers?
You do not need a tune with any header.
Do I need a tune for equal length headers?
Is a shorter exhaust pipe louder?
It will probably get deeper witht he bigger pipe… if you use a smaller pipe it will be more high pitched. The “Loudness” is controlled by the muffler.
How does exhaust length affect performance?
Internal combustion (IC) engine exhaust system can influence the engine’s performance in a significant way. This paper shows that a variable exhaust manifold runner length can improve the engine performance in terms of its output torque by over 10% especially at lower engine speed.
How many horsepower will headers add?
If you’re wondering how much horsepower do headers add to a 350, it’s about an extra 16 hp for long tube headers. Shorty headers won’t give as much, but you can count on a similar increase of about 6 hp, generally speaking.
Are headers better than stock manifolds?
Why are headers are a better choice than an exhaust manifold? As stated above, exhaust manifolds create back pressure, which lowers performance. Because each cylinder of the engine is given its own tube, however, headers eliminate this problem; thus, allowing the gases to exit without the creation of back pressure.
How much horsepower does aftermarket headers add?
Does an up pipe require a tune?
The uppipe would not require a tune but can be run on the Stage 2 map as long as you have the correct hardware for the rest of the vehicle like a catted 3″ turboback exhaust.
Does an AOS require a tune?
The advantage of the Street AOS is that because it retains the same connections and intent as the factory plumbing, you can install the Street AOS without needing to tune the car for it.
Does length of exhaust pipe matter?
Proper exhaust-pipe size is a function of both engine output and displacement. Proper exhaust-pipe size is a function of both engine output and displacement. The higher the engine’s output, the larger the pipes should be. Likewise, larger engine displacements call for bigger pipes.
