I was driving home from work today, admiring the beautiful note of my Europipe Stage 2 Loud exhaust which is regularly interrupted upon even the most modest acceleration by what I believe to be a whistling boost leak, I was wondering what the difference in output is for the IA-GT640 when comparing the Europipe Stage 2 Loud with the Fabspeed Sport - the Exhaust around which the package was designed.

I really enjoyed the comprehensive analysis Stephen did, some time back, on several different exhaust systems, but apparently the Europipe data was flawed. I heard a revised version was posted somewhere with correct data for the Europipe (quiet) but have never seen it. Does anyone know where to find it?

Interestingly enough I also have a Europipe Stage2 loud on my EVO stage4gt turbo. EVO MS recently ran back to back dyno's on my car with the only diff being the exhaust (EP vs FS) with FS showing significantly more power in the 4k to 5.5k range (in excess of 40hp and 40ft lbs) then narrowing but maintaining an advantage to redline. I love the EP for it's build quality and sound but can't ignore the FS performance. I'm told it flows better for my current programming even though EP uses wider diameter piping. I'm considering the change if the FS loud is not too loud for me and has no major resonance issues.
