Why are exhaust manifolds the first line of disappointment?
Exhaust manifolds are generally the first line of disappointment when it comes to exhaust routing. Because the cast construction has been designed for ease of production, they are generally heavy, and do not offer desirable mingling of the exhaust pulses.
How does a properly engineered exhaust system work?
In a properly engineered exhaust system the primary tubes are clocked in the collector to orient the firing order in a circular pattern. The pulse pattern generates a swirling effect which further improves scavenging. Merge collectors are labor intensive to fabricate.
What should be considered when tuning an exhaust system?
Tuning an exhaust system to a given application is a case-by-case basis challenge. The displacement, exhaust valve size, induction system, cam profile, exhaust port design and RPM range all factor into deciding what form the exhaust system should take.

What should I consider when designing an exhaust system?
You cannot simply select a random collection of exhaust parts and expect to realize top performance. You must take into account your engine displacement, head size, cam timing, intake design, carb size, and other aspects of the engine package. You also need to consider intended operating RPM, application, transmission type, and other factors.
What kind of coupling surface do you need for an exhaust manifold?
Most later-model exhaust manifolds feature a ball-style coupling surface for exhaust pipe connection. This provides more flexibility for achieving a good seal at the installed angle. Always replace used studs with new studs.
How can exhaust manifold design improve combustion efficiency?
Combustion efficiency of the engine can be improved by improving the exhaust manifold design in internal combustion engine. Performance of the engine increases if the exhaust manifold is of a good condition.
Where is the exhaust manifold in a multicylinder engine?
The inlet of the multicylinder exhaust manifold is connected to the outlet of the multicylinder heads. Exhaust manifold is attached to the engine and major part where the stream from different cylinders is to be collected into a one pipe in multicylinder engines.
