It's about the same volume as the stock coupe exhaust which is perfect for me. Too bad it doesn't work those with and x.
OP, I would go with tanabe if you can stomach the rocket booster look.
The tanabe tips aren't much different in size than the fx35 that I saw the other day with a factory setup.
I recently removed my Stillen carback because that system is very loud! Believe me and now I am selling it. Gonna post it up here soon. My buddies have Ark and Fast Intentions and they are annoyingly loud too. If you like a lot of drone in your cabin and people hearing you a couple of blocks away then I highly recommend Stillen, Ark, and Fast Intentions. Now I have Invidia on my sedan and it is very mellow. It is louder then stock but not by much. It sounds more like the coupe but only a tad bit louder. I definitely recommend you getting Invidia if you are looking for something that sounds great and isn't too loud.
Thank you!!! Finally a comparison of these exhausts. 
Does the Invidia fit the AWD? I thought I read it did but I can't find that post anymore. Can someone confirm AWD fitment?

I couldn't be happier with the invidia on my rwd. Just the right volume, and if I do want louder down the road, I'll just add hfc.

What qpham45 said about stillen, FI, and ark is consistent with everything I've read on these forums. While they do sound good, it's pretty easy to tell they're aftermarket when you hear one driving by.
