CHP vs. Magnapack

[01GTPony]

I'm thinking about putting a magnaflow cat-back w/ the magnapacks on my '01 GT. I'm curios if anyone has had trouble with this system and the CHiPies. Also, how much louder than stock is this system?

it will be loud..just don't get on it when passing CHP

With the stock H-pipe, it's really not that loud....

Is it true that if you have an o/r xpipe and magnapaks and you add bbk lt's, it tones down the sound?
