[QUOTE="Kevin Lang, post: 758087, member: 65699"] Cooler exhaust noise is subjective, though I do think that the stock exhaust sounds corny. Ideally, exhaust shouldn't exist. However, I know that internal combustion isn't perfect, and that exhaust is a sad necessity, and that streamlining the exhaust process will, to an extent, increase performance, though after you pass a point on restriction, you seem to have to sacrifice other elements to make gains in the 'performance' region. Adding more air is supposed to increase the efficiency of the burn, so that there will be enough air for all of the gasoline to combine with. Increasing efficiency should thereby reduce exhaust amounts. If you increase your exhaust by adding more air, then it would seem that you are putting too much air into the engine, going past the ideal point for air and fuel. Having to buy a new exhaust set up to deal with your increased air input doesn't compute. [/QUOTE]
