OK, so I am new here, but have been watching this board for a long time in search of information.

There is a lot of talk about exhaust systems in this forum and we in the US would like to know what exhaust makes the best power on the 01 and up WRX. We all know of Scoobysport which is sold in the US, but there are a number of other brands here and much combining of brands going on.

The big debate stateside at the moment is 2.5 inch vs. 3 inch internal pipe diameter for the car. You guys have loads more experience with the car, what do you think? Is the Scoobysport with the 2.5 inch pipe big enough? Are there any other manufacturers with dyno-proven power gains on this car? Scoobysport is the only one I know of anywhere known to make consistent power regardless of other modifications made to the car.

Thanks in advance,
