Why Do Macs Rasp Really Bad?
BTW the ycollector on the macs is not 3" in diamter like they advertise. More like 2.75"
The Flowmaster collector should help kill a little of it.
But it's mostly a no cat issue. Because with cats, Mac's don't rasp(nor do any other headers).

I just hope a bigger muffler will quiet it down. Another thing I though of tryin was runnin 3 bullets. 2 2.5" bullets in the y and one 3" bullet in the Ipipe.
