Exhaust system ofr jumbuck
you can go cheap and use a common bend extractor and regular exhaust system or you can get better with a mandrel bent extractor. Use performance muffler and pipes about 1/2 inch bigger than standard . Extra large looks good but will reduce performance and the cost will not be worth the effort. Exhaust systems to work have to be tuned to the engine . They have to be designed so that the shock wave from a power stroke enters the extractor at the exact moment that the previous shock wave that reached the end of the exhaust pipe has turned into a low pressure area and travels back to the extractor to arrive at the moment the exhaust valve is opening so allowing the compression gas from the power stroke to exit into a small low pressure area which in turn sucks out the used gas. That is why wrong size exhausts area a waste because the low pressure hits the exhaust valve and becomes a high pressure area as it rebounds back down the pipe and the exhaust dumps the power gas into a pressure area and not a vacuum. There are books on tuning exhaust systems that will explain it in more detail but you will find that bigger is not better . It just looks tuff and noisy and is next to useless when it comes to performance.
