Just installed a full HMF exhaust tonight. I knew the HMF header had a larger diameter, but didn't 'how much larger'. Anyway, so I took a couple of pics before I put it all together. I didn't do the best job though. At first glance, it looks like the stocker has a larger 'mouth' where it bolts to the head. But if you look at the 'mid pipe' sections and the end that goes into the header you can see the HMF is definatly larger in diameter.

Man, I won't sleep a wink tonight thinking about firing her up tomorrow and taking a spin on the seat-of-the-pants dyno!!
