1991 GMC S15 Sonoma Exhaust Manifold

For many engines, high performance after-market exhaust headers are available. These consist of distinct exhaust head-pipes for each cylinder, which then ordinarily come together into one tube called a collector. As an motor starts its exhaust stroke, the piston moves high up the cylinder, decreasing the total chamber volume. With the exhaust valve open, presurized exhaust gases are forced out into the exhaust manifold or header, causing an exhaust pulse.
