Never mind, i guess 30nm is only around 2x lb-ft... Just seems tight because the clamp ends are making full contact and my torque wrench doesn't even click off at 20nm yet.

I think this might be a lost cause and the X might just be one heaping pile of crap. One flange connection is perfect, the other leaks horribly! I have one more thing to try... I keep telling myself that... One more thing.

Now I think would be a good time to go to the hospital. I'll check in with you guys later after I get to drive it some.

While I can't speak for the FRPP pipe, the Corsa said to tighten down the cat flanges before mounting anything else to the system. I had the front lined up no problem and tightened down before connecting the mid-pipes and never had a leak up front. I did, however, have to use some copper make-a-gasket on the driver's side portion, where Corsa decided to split the pipe. It leaked like a sieve right at that joint. Thinking of getting it welded in the mean time.

What I ended up having to do to get this to line up properly was use a loop ratchet on the cats right ahead of the flange to pull them together about 1/4". After i applied a generous bead of high temp silicone to the x pipe flange, I used a second loop ratchet to pull the X pipe into the cat flanges. I did all this while the mid pipe section was supported by a box at its normal height.
I made sure to orient the clamps exactly like they are in Modshack's picture and then tightened them securely. I removed the loop ratchets and then tightened the rear flanges. This seems to have done the trick, but only time will tell... I need to drive it and see how it holds up.
Overall this has been one of the worst experiences of my life.

Ok, driving impressions:
This DEFINITELY is no for you if you like a more traditional American V8 sound.
If you like a more refined, European sound, read on:
The X pipe did everything I wanted and expected it to do with the sound. Like Steve mentioned, the exhaust sounds a lot smoother in general due to the blending of the exhaust pulses. With my FRPP Sports / Borla S-Types the exhaust sounds a little bit quieter and more tame under normal acceleration. The H pipe was a lot more raucous and unrefined. The X sounds tuned and has a much higher pitch to it than the H.
It has a lot more of a wail to it compared to the roar of the H. It sounds fantastic in the mid range especially. In a way it sounds like the old 2v 4.6 liters now. It doesn't have that hollow sound, its more meaty, but it definitely has the wail.
On deceleration / coast down the exhaust sounds a lot smoother as well. It isn't anywhere near as raw or crackly as the H pipe. It definitely sounds aggressive, but no longer does it sound obnoxious and unrefined.
Needless to say, I am extremely pleased with the sound. I prefer a more refined, Euro tone and this definitely delivers. I am very happy with it. If you prefer a more raw sound then you should probably keep your H pipe, but if you're like me then you cannot go wrong with the X pipe.

Put around 70 miles on the car today further confirming how much I love the new sound. I thought my FRPP Sports sounded really good with the H pipe, but now it's a symphony. I like my cars to make music.

Wondering if I should go Corsa or FRPP for the Xpipe.

If you go Corsa, you're probably going to want to have it welded in one piece. I did, however, have zero issues with fitment on the cat side of the pipe.

Now that Steve and I have both worked through the FRPP X install, I think if future installers read through our install notes they probably shouldn't have a problem. You just have to go into it knowing it's a PITA. The tie-down straps I used to force everything into fitment really helped. Because I only had the front wheels on ramps I think this is the only way I could have made it work as there was no way for two people to get enough leverage to force it.
Also, as Steve suggested, I think after a few heat cycles everything should be in good order. If I were to remove the X pipe after it had a chance to "break in" it probably would go on a lot easier.

eh... looks like I'll probably scratch this one off my list as well (heart throb is off teh list too)
I may just take my car to our local exhaust shop. They've built 2 of my exhausts so far and they do all the work on the drag/race cars in town.
the corsa mid pipe may be another option though.. or the bassani. I had the bassani o/r X pipe on my 97 GT and it sounded amazing.
