Ryanm8, what did you do to fix it? Mine sounds like yours, but multiplied by 10.
I feel very confident you rasp is from this, as mine was. I would research a y pipe that has a HR design merger and the appropriate inlet and outlet you your art pipes and rear muffler section

Theres no point of him gettin a y-pipe unless his plannin on selling his HKS.

Buddy of mine had crawford hfc & hks exhaust and had rasp like a honda.
Switched to a X-pipe instead of his H-pipe solved his problem.

Im not sure if u read the post someone posted on here showing the low quality welds the inside of the H-pipe from the HKS exhaust has. Might be the problem.

Good Luck!

If your exhaust combo is a combination of different inlets & outlets. That plays a big factor on the flow of the heat inside the exhaust. causing hissing & rattles.

If you run an oem HR/DE y-pipe with HFC or TPs your always going to get some sorth of noise. Since hfc/tps outlets are 2.5"-3" & the y-pipe inlet is 2"-2.25"

I might not be right but thats what I learned from my experiences.
