Easy JD you know how the noobs don't like being picked on.
over priced sounds like crap, never heard a borla I liked.
Magnaflow packs[sm=icon_rock.gif][sm=smiley20.gif] kick ***. Love mine wouldn't dream of any othe catback.
Seeing as you have kids. The magnaflow regular system is nice, not as loud as the pack, but still a nice clean sound.
If you don't want to be terriably loud then go with the regular packs.
To really see any performance though you are going to need to swap out the H for at the very least a catted h, I would recommend a catted x-pipe to keep everything legal. The mid pipe alone should net you 8 rwhp, that is more then the catback alone would get you.
Skip the TB, upgrade the MAF. The TB will hurt performance. You can only take in enough air as the motor needs. The easier you help it breath the better.
I would recommend a C&L set instead of the densecharger. MAC makes okay stuff, but I have never heard complients about a C&L setup.
