Factory CAT Questions
I have a piece of 4" exhaust pipe, what size is our factory exhaust? I measured the tailpie and its 4" but it looks like it flares out, is our factory exhaust only 3"?
If I cut the cat out will the 4" Piece of pipe I have work? What other precautions do I need to take? Do I need to unhook my batteries before hand? Will it through a code if I don't?
Thanks!!

for working on the exhaust they recomend you do disconect the battarys but i never did while puting my stacks on, also the stock exhaust is 3" from turbo down into a four inch tip. if you have a 4" pipe already it will not work it is to big, unless you buy two bell reducers from 4" to 3" but i recomend buying a new 3" pipe to replace it. Also on mine i have the stock down pipe into 5" flex tubing all the way to my stacks
