Tom, What rear header are you using? Stock?
PS, I hope you used VHT High temp paint, cos the Duplicolor stuff won't stand a chance.
Also why does your downpipe flange point up at the end, instead of straight back?
PS, you might want to plum that Wastegate pipe back into the exhaust, cos mine is now and it is STILL LOUD! Dumping to atmosphere like that, unmuffled, is going to be crazy loud!
