Have a couple questions. Im thinking of having a catless midpipe made and need some info. First do i need to buy a programmer for this to work, and the truck to run right, or can i just buy a set of mil eliminators and get buy. Second im still contlimplating on wether just to get a magnaflow hi-flow cat mid pipe. Where is the best place to pick one of these up for the best price. Thanks alot

 

The stock cat pipes each have an O-2 sensor before and after the converters. The front sensors monitor what is going into the cats and the rear sensors monitor how well it got cleaned up. So, with that in mind, something in the program has to change or the truck is not going to like what the sensors are seeing if there are no cats in the system. The Magnaflows work well and can be run with ot a program change, at least when they are new. I don't know how long they'll run before they don't clean it up enough. The stock system has two cats in each pipe.
