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..
Do shorty headers make your car louder?
Shorty headers are usually a little louder… especially at part-throttle and Idle.
How much HP gain from headers?

Do open headers add horsepower?
The answer won’t just be yes or no. Usually an open exhaust decreases low rpm power and increases top end power. There’s a perfect amount of backpressure that makes the most power at a given rpm.
What year is the best Chevy 350 engine?
L31 (2002) From a purely technical standpoint, the most recent version of the Chevy 350 would naturally be the best of the bunch. Marketed as the “Vortec 5700” engine, but known internally by the moniker of L31, this engine was used primarily in GM vans and trucks until 2002.

Do shorty headers make a difference?
For shorty headers, the port pipes actually merge into a single exhaust pipe in a much shorter distance. … Because of this, each design impacts back pressure in the exhaust system in a different way. Longer port pipes result in lower exhaust back pressure. This means improved oxygen intake and a boost in horsepower.
Will shorty headers bolt up to stock exhaust?
No. Your stock y-pipe will not fit long tube headers. If you are looking for something that will fit the stock y pipe go with shorty headers. There wont be much if any difference as the converters are part of the y pipe.
How much horsepower do headers add to a 350?
The length of the primary tubing determines the effective rpm range, but headers can be worth 15-20 hp on the right application. Run on our restrictive two-barrel 350, the headers improved the power output to 248 hp and 365 lb-ft of torque, with consistent gains through the rev range.
