One of the most common questions in exhaust design revolves around header diameter and length.
We have established that an engine cannot produce more power by adding silencer boxes. This is true. However, having said that, there have been instances where power gains were obtained in race prepared cars with the addition of a silencer box.
With over four decades of experience working on exhaust systems, especially performance exhausts for two-stroke and four-stroke bikes, road cars, rally cars, hybrids, and even kit cars, I’ve seen it all.
We’ve spent a lot of time discussing branch manifolds and explored the factors that impact the performance of header pipes, secondary pipes, and various branch designs.
