Do you really think you will be able to feel
the 2-5% gain(at best)? Lots of people say they can, but I suspect it's all psycological and mostly they appreciate the difference in sound = Louder sounds
faster. 3-4% is nothing.
The electonic fuel management mods make a bigger difference, and you would want it with the exhaust anyway. Start there.
