The Ark exhaust does hang pretty low. Surprisingly...I haven't scraped my Y pipe but once. Its more the tips and cans on heavy inclines.
That's a fantastic photo.
There's a reoccurring theme from ARK owners: "Yeah, it scrapes, but oh man the sound!"

Anyone have an opinion on FI's CF mufflers? This is the first I've ever come across it.

I've thought about that. You think FI would weld on those Red Tails? 
And if FI, pretty sure I'd go with 18" resonators. I'd only like it hella loud if it "pops!", like the Ark or Motordyne.
What I'd really like is if Fast Intentions sold a cat-back with a helmholtz resonator. That would be the best.

After thinking about it if not for the deal I got on my MXP then I might have gotten Motordyne just as well, but since I got the deal and considering the MXP is not too common I wanted to distinct myself from the rest of the crowd and be different
and I'm pretty happy with the outcome. I feel like we need to meet up once again before you pull the trigger on an exhaust and You need to hear it again !
Well, those are the objective facts. Some people claim a higher pitched sound for the CF, while others say that the sound difference isn't that much.
I found a quote from the370z forum:
"The Carbon Fiber sleeve is technically not thinner than the Stainless Steel case. The reason it dissipates the sound differently is mainly due to the material characteristic of one to the other. It is also due to the way Carbon Fiber muffler seals to the end cap vs the Stainless Steel being welded all the way around.
Thanks, Tony"
