Default For those of you that have cutout on the gxp

I am about to order a DMH cutout. I am thinking near the back is where I am going to install it. Is the exhaust 2.5 in? Also does anyone have DMH what do you think?

Thanks for that. I think I have determined where I want it. Was just looking to see if anyone ran DMH?

2.5" I'm sure. Mine replaced my cat. Thinking about moving it back a bit to where the resonator is supposed to be.
