Which is better a shorty header or a longy header?


Asked by Brooklyn Henry on Dec 05, 2021 FAQ



Shorty headers are also a better option for states that require emissions approval. What’s more, they’re generally easier to install. If you’re going to the track, you might be spending more time running higher RPMs.
Next,
What sets shorty tube and long tube headers apart is the length of the primary tubes to the collector. For "shorty headers," the port pipes actually merge into a single exhaust pipe in a much shorter distance. For long tube headers, the exhaust pipes are much longer (about 28") and merge farther out.
Keeping this in consideration, Shorty headers give your exhaust manifolds free flowing piping that'll improve the performance of even a naturally aspirated motor. But short tube headers really shine when they're used in conjunction with a turbocharger - their more compact size fits nicely in the engine bay right alongside your turbo flange and piping.
Additionally,
Different style headers provide varying sounds and power. Long tube headers supply the most power and increase the vehicle's sound. Mid-length headers give power ratios and sound qualities somewhat less than long tube headers. Many people want their vehicle to sound good on the street, but in many cases, it can be unbearable inside the vehicle.
Similarly,
Long tube headers are a great option for high revving vehicles to allow for a lot of top end exhaust gas flow. The difference between these and short tube headers is the length of the primary tubes to the collector. Long tubes keep exhaust gasses separate from each cylinder for a much longer period of time.
