Hey SickSix, I have BBK shorties, h-pipe with cats and a flowmaster catback. A lot of guys on here will tell you to stay away from BBK, I kind of agree with them. The headers fit pretty good, the h-pipe needed a lot tweaking to get it to fit right. Once I managed to get it bolted up it seemed to fit *OK*, it still hangs a little too low and I have a small leak. So I would recommend their headers, (go with the ceramic coating if you can afford it). But I would say run a different brand h/x-pipe, maybe Bassani or Magnaflow? Their a little pricey but you get what you pay for.

BTW: Where in MA are you? I'm out in Worcester.

I have mac shorty headers, upr offroad x pipe and American thunder after cats. It all actually fit together well. It all really depends on how much you want to spend and what you want to do. H pipes sound a bit better, x pipes scavenge a bit better. Personally I really like the flowmasters on a 5.0. I have more of the low end in money but I like the sound and the offroad x pipe makes a good difference under boost.

Mac shorty's, forgot what brand O/R H-pipe and 40 s Flowmasters with tailpipes in stock locations. Sounds great to me. Just had the shorty's installed and we had to bend them just a bit to clear the steering coupler. Had a heck of a time to get all to line up on the driver side with the head part. Finally got it though. Had alot of folks say'n I should of gone with LT though. OWell there on and im satisfied.
