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

That sounds fantastic. I heard no raspiness and sounded like it can blow the fur off a cat. My PPE's have so much rasp, you'd think I had a baseball card stuck in my spokes. I think if I had a second chance at spending the money that I did, I would say screw the cat I was trying so hard to get back on and do F.I. 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. :ugh2:

I love my LTH + 18" CF set-up

Just gotta be different with the CF cans. :yum:

I wants CF Cans too. :icon17:

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
