2010 Mustang GT Pypes Exhaust

I have the Pype Bomb on my 2010 as well. Sounds awesome doesn't it?! I would try taking video outside of a parking garage though (on a day without wind noise), it makes it really hard to hear the sounds well. It's loud, but there's a lot of extra noise reflected when surrounded by concrete that drowns out the actual exhaust note. How much louder is it with the O/R H? I'm trying to remain on good terms with my neighbors!
