The Hiss is classic F.I. sound, completely normal. It just goes to show how free flowing the exhaust is. Nothing but backpressure.

I spent $2800 for mine and I could have gotten this for the same. I'm even thinking of getting rid of the cat and adding a 3rd resonator just to make the rasp go away!

I don't believe the PPE Headers are Equalength, which would explain the rasp.

The PPE headers are equal length but the merge collector is higher up and the tubes are stepped. In hindsight, I would still rather do the F.I. headers because they sound better. My gained were fantastic though
