Exhaust manifolds are generally simple cast iron exhaust system parts which collect engine smoke from multiple cylinders and dispense it to the exhaust pipe. Great care must be used when selecting the length and diameter of the primary tubes. Tubes that are too large will make the exhaust gases to expand too fast, cool, and slow down, decreasing its benefits, possibly sacrificing engine power.

For lots of motors, after market high performance exhaust manifolds are offered. These consist of separate exhaust head-pipes for each individual cylinder, which then usually converege into one tube called a collector. Be careful when selecting the length and diameter of the primary tubes. Tubes that are too big will cause the exhaust gases to expand too fast, cool, and slow down, decreasing its benefits, possibly losing engine power.
