The best solution to reduce volume and rasp is to do one of a few things.
Go back to stock header
Switch out your Catback Exhaust for something quieter like the Q300, R400, Perrin Ressonated 2.5" CBE or the 2.5" Nameless Axelback with 5" Muffler.
Sell your current header and buy a catted header.
There is nothing quieter than our stock front pipe. I have switched mine out for the JDL ultra quiet which has a high flow cat and resonator and its still louder than stock.

Yeah agreed. Swap your catback for a Q300 and keep your stock FP and the PSR headers.
I've got Tomei UEL headers which are pretty much the same as the PSR's plus a Q300/stock FP combo and the noise is noticebly better than stock, but not too loud or raspy. The only time I ever hear rasp is through first gear if I launch it on a cold day.
