Opinions on the Magnaflow X pipe cat back. I see from several posts that it does make added rwhp (seems like about 12 rwhp give or take a little). My question is: does the increased rwhp from this system come from the X pipe, removing the stock resonators & mid muffler where the 2" diameter pipes are located, or replacing the stock axle back mufflers, or all three? If all three, where do you think most of the rwhp gain comes from? Thanks in advance for your input.
