Pretty much. If you have stock exhaust its just gonna be stock exhaust but beefier/louder etc. Havin a little rasp with the heat shields (I think). I noticed it tonight while on an incline but went away after I was level again.
I'm getting mine done this weekend so i'll let you know.
All Crawford HFC owners I've read have passed inspection. I even asked Crawford directly and they said it will.

cool, let me know. thnx.
yo! i got a HFC question.. would it be wise to get HFC's first then a Y-Pipe upgrade and THEN get the rest of the exhaust? im tryin to figure out my priorities with these pricy upgrades 
I'd go HFCs... That's going to reap the best gains for you PERIOD throughout your exhaust, since it's the most restrictive to begin with.. on a naturally aspirated car, you're going to get minimal gains w/ the exhaust or Y pipe.. I'm still rockin a Stock Y pipe, and because it's a smaller diameter pipe going to a larger diameter(midpipe and mufflers on exhaust), I'm getting more back pressure yielding more torque...
But without a doubt, go cats first... That's what I was rocking for a while and was very happy.. should be first priority, hands down. You'll get some HP and torque as well from the cats.
Berks, Kinetix, Crawfords, and Fast Intentions seem to be the most popular.
If you're going w/ something after that, I'd say go Exhaust..
I'm thinking of getting a 350z y pipe, almost had a G37 y pipe but then started reading that the diameter size of the inlets being 1.75" (smaller) than the normal 2" inlets from the cats, actually make you LOSE power.. so I said HECK naw.. I'll wait for a 350z Y pipe, but they're so freaking rare for people to get rid of from what I see, but I hear of them going for as cheap as 50 bucks shipped... maybe I just have bad luck..
To sumarize..
1.HFC
2.Exhaust (if you're NA, then axle-back, just midpipe and muffler)
3.Y-pipe
my .13 cents.
