Wonder if this really works.. It looks very nice flush like that.You could weld in some resonators. Alternately, and I swear this sounds crazy but it's legit, if you rotate the tips 45* so they match the curve of the valence, it drones less. (and looks cool)
Like so:
Try running the MBRP race with no tips at all, you'll want to ventilate your skull within minutes. I'm no sound engineer but it seems that the bumper catches the exhaust sound pulses and directs them back at the car. I specifically adjusted my tips to be past the bumper all around and it changes it drastically, although mine is an EB not a GT it should still be similar.
Last time I pointed out to people that 2K in 6th is the wrong gear to be in for those RPMs and speed, that most any exhaust will droan in that situation, they all shit their pants in revolt. Next lower gear will pull more RPMs and keep you out of that dreaded 2K range, just because the car runs and goes down the street in 6th @ 55mph doesn't mean that that's the correct gear for that situation.
This is probably the least invasive way to handle it. From my own interest I looked at resonators added to the H-Pipe and didn't find much that wasn't basically ripping out the entire midpipe and starting over.
