Search is your friend! There are about 7/8 topics already discussing this, and some with dynos!

 

spipe and catback exhaust. dont do the catback w/o the spipe because you are going to be losing hp due to the pipe going from larger, (smaller where the current spipe is), then larger again where your catback will be. just my 2cents.

 

how loud is your current setup? I have the k&n and was looking into a different header but dont want to ruin the sound I have now. I like the grunt the intake has and the quietness of the stock exhaust.... did you notice any slight performance gain when you added the header w/o touching the other parts that are restrictive (meaning the spipe and catback)?

 

I added only an alphawerks header and it defninitely picked up a few hp. It feels a lot more consistent, and pulls a lot harder in 3rd gear.
