what about the fitment was off?
I got it on, fitment was spot on. You DO NEED new hardware nuts and bolts the hook the headers to the xpipe. They are studs on the original and 2 of them won't come out due to not being able to clear the cat. Rear clamps work just fine. I put a clamp on mine where it's two pieces and meets just for a piece of mind that it won't leak there. It does seem like it hangs down a bit more than the original but honestly don't know how much the original hung down so maybe it doesnt but looks like it does to me.
Here is a vid with sound. No revs though. Sorry!

I honestly didn't do anything fancy on my fitment. Took original out and slid new in. I didn't loosen muffler to over axle pipes at all. It actually straightened out my muffler tips some and made them stick out a little bit more which is what I wanted. It just straightened mine by accident and I didn't have to really do anything.
Nice! You do have the gt500 mufflers though, not jure what Jason has. You got new bolts and nuts for the headers though right?
I have the bassani race axles. Were all your pipes even or any sticking higher than the other?
