Message	As hot gasses expand, they cool. Cool exhaust doesn't flow as well as hot exhaust. Therefore, by going up to a 3" pipe instead of a 2 1/2" pipe, the flow of air is slower out of the pipe with a 3" one(more volume to fill). Slower exhaust velocity can ultimately lead to backpressure at certain rpms. And ANY amount of backpressure is bad(i.e. this is why dumps are good on a turbo car). Not only that, but typicly a 2 1/2" system is gonna be cheaper than a complete 3" system. Why spend more money if it's not gonna give an increase in power? Unless you've got ricer thinking where bigger is always better! 76 280Z 89 Sunbird GT Turbo 9.7@73 mph 1/8th mile 02 Accent GS
