to me raspy is that poping/sputtering after letting off the gas, you can hear it plainly in the vid above. my truck does it too. the guy who posted that he got the H pipe installed said it got rid of it. and it makes sense to me. equal pressure on both sides before the Y-pipe collector. I'm hoping to get one or an X-pipe to gain a little power and cut down on the sputtering. I have a flowmaster 40 series and hate that raspy crap. sounds un-tuned, I'd rather it have nice growl deep and what have you, but clean sounding like a tuned mustang exhaust
