i have been looking around for different types of boxes to give me more under the hood and was wondering how other's like bully dog power pup with outlook monitor? or are there better ones for the money? also is it worth the extra money to go 5 inch exhaust or just stay with 4 inch?

stay with the 4 inch.

also the bully dog stuff is good stuff, but I also like the Van Aaken C3.2 box and the Quadzilla box.

right now I'm looking for one that leaves the smallest footprint in the ECM incase something goes wrong the scanner wont pick it up

but with me buying a house next month and getting married at the end of this month my finances arent looking to good twards hopping up my dodge[&:]
