You can get a high flow catted X or H pipe or not, if you don't have emission tests. But between the 2, HP gains with no cats will be minimal.

I have a 19973.8 with the stock y pipe and i was looking at getting the flowmaster super 44 but i was lookin at the exhaust and it looks like it has 4 cats one set directly off thr headers at a downward angle then it levels out and directly after there is another set.? are all of these cats and if they are could i just take a set off for a little more flow? i hope this ? doesnt make me out to be an idiot but ol'well.

thanks
