Wow, I completely forgot about this thread. Sucks that 2.5 years later folks are still fighting fitment/alignment issues. It really is a very nice system but damn if I don't curse that misalignment of the two cans, every single day of my freakin' life.
I can tell you guys that after 2.5 years of daily use, (a year of that in road-salt plagued New England), this exhaust still looks like new. Cans polish right up to a mirror shine with a quick wash of soap and water. No signs of corrosion. No rattles. And still has the best sound of any exhaust system I've heard to date on a 370. Totally biased opinion on that exhaust note but whatever.
If ARK has fixed the can misalignment problem and now it's just a matter of a finicky install, I really don't think you can go wrong with this exhaust. Not for the price. Yes their instructions are lacking. Yes the install is tricky. But once you get it dialed in and fire it up, OMG you'll never know how you lived without it.
I have a buddy that used to do all the chassis welding for a top fuel team. I'm seriously thinking of having him cut the left can off, rotate it 15 degrees, and TIG it back on for me.
