Enough. Get it dyno'd.
"SBC headers" typically refer to shorty headers for a Small Block Chevy engine. These headers are aftermarket performance parts that are designed to improve exhaust flow, increasing engine efficiency and power output. They are often used in high-performance applications or custom builds.
if you have EFI engine, replace your stock intake, headers, exhaust. installing racing filters improves air intake which can add power to your engine. replacing your stock headers and exhaust pipes with custom headers and mufflers can eliminate back pressure. doing this upgrade can give you additional 10 - 20 HP.
upgrade the air flow! cold air intake,headers,hi flow exhaust and if you are up to it get a port and polish you can even do it yourself i have done all of these and it has gained a lot of power what ever you do don't get the hypertek programmer it sucks.
there are some good headers and exhaust out there like a flowmaster for the 200o will give a extra 25 horsepower for 400 bucks and headers will give about twice that cold air intake, high flow cat, pulley system, headers, exhaust. also aluminum driveshaft will reduce weight and allow more power to the wheels and better rear gears will help get more power to the ground.
Intake/exhaust/programmer can give you-10hp-20hp. Anymore you need a cam /intake and or supercharger/turbo/nitrous.
Installing a after-market exhaust will Increase MPG and low-end and high-end power outputs. Also with addition to headers will come Increased loudness and Horsepower and low-end torque.
they alow the motor to take in more air via intake and evacuate more air via exhaust. thus creating more power. in short the more air and fuel you can move through a motor EFFICIENTLY the more power you will build.
yes
The answer to this question depends on a variety of circumstances: 1. What size is the engine? Larger engines benefit more greatly from increased exhaust flow in most cases. 2. What size headers are you thinking of using? Choosing a primary diameter that is too large or too small may reduce your total power. 3. Headers alone may not have much effect on power if the engine already has a decent set of exhaust manifolds and/or has a restricted intake system.
intake manifold and headers or replace with 350
intake compression power exhaust
Intake compression ***** POWER**** exhaust
