You guys do know the thing with exhaust systems correct? The larger piping we put on our cars takes away torque for the sake of adding more power up top. Thats why when you read the mfg. recomendations they are giving you the best "in the middle" so to speak. There was an arguement a while back between a bunch of n/a ka guys that were running 3" pipe. People were telling them they weren't making anymore horsepower but they were...they were just losing torque. So in short something along the lines of a 2.5" exhaust would give you a good midrange torque curve but is just too restrictive for all out horsepower. Now dont get crazy and attempt to attach 4" piping because of what I've said here, most of us aren't making enough power to actually benefit from it. On another note... those are great numbers, I'd like to see the graph if you could. I'm suffering from boost creep/ spike/loss whatever and I'd like to see what I should look like.
