G37 clip - YouTube
you can hear the noise in this clip...it's the same pitch as the deceleration hiss

that is the exact same sound my car was making. we put it on the lift with someone in it... sound came from dead center of the xpipe.
we then ran a smoke test and had a small leak at the flange driver side infront of the xpipe

I just tightened all the sections of the exhaust except for the part that connects to the headers and the sound is better. I think it just needed a little tightening after the initial install. I am goin to make some good gopro vids now that its better. thank you for the help

Dyno F.I CBE, RHFC
I have had 2 uprev tunes done on the car..
First one
F.I. catback and Stillen G3 intake.. done mid august
intake and CBE were installed before I headed to have the car uprev tuned so there is no stock run..
The second graph has a trq spike that I was told is software glitch..
second graph is after the addition of F.I. RHFC.
I had a small exhaust leak at a flange.
I replaced the gaskets today and I am still getting a hiss at acceleration and with the car in park and you hold rpm at 1300-1500... Tony heard the noise and said it is either a leak or the xpipe.. the shop that installed the replacement gaskets today Thinks the sound is a baffle in the xpipe.. noise comes from dead center of the xpipe.
First dyno temp was 91 humidity was 88
second dyno temp was 87 humidity 74

This is from back in the day when we did the R&D on the new (at the time) V36 sedan:
My morning at Fast Intentions ... - G35Driver
I had the FI exhaust on my car forever and my car worked great with it even with twin turbos.

Its been about 150 miles since I installed the Fast Intentions Resonated High Flow Cats on my 2011 G37S Sedan.
At first, there was vibration due to this part not being removed. So make sure to remove that part (especially if you have the stock cat-back)
Anyway, after it being removed, everything ran great.
So, I while be dyno'ing it soon and I have a before graph to compare so I will update. Sound is almost stock like except at high revs which is a bit more noticeable but still not loud. I wanted a stock-like sound with better performance so that is why I chose resonated. Was a bit disappointed with the wait time, but can't complain about the quality.

Ok will do! but I'm not good with reviews 
2008 G37 Coupe 5AT
SS, 12", Xpipe Upgraded
I have OEM cats
Also have Stillen Gen 3
The parts came in packaged nicely and took a while to unwrap them all. I took it to a friends shop and he installed it in about 2 hours.
I like the way my exhaust sounds when I'm cruising it's not loud but when I step on it, it comes alive! Also, I never noticed the VQ hiss sound with my stock exhaust but with the FI I'm loving it!
I plan on getting the FI RHFC within a month or so and I will make another video with them on. Now that I have these bad boys on I feel like more people wanna race me hehe
I took my G to track when it was stock and got 13.7 but I will take it to the track again in spring and see if I get a better time with the FI exhaust, FI RHFC, Stillen Gen 3, UpRev Tune and maybe the M370 intake manifold.

I was recording because I wanted to see what the car sounded like from the outside. My brother was messing with the DS mode in the begging of the video

Figured I would post this.
I have Takeda intakes, the X-Pipe upgrade and the oval mufflers. As well as the FI HFCs.
There was a slight voltage issue which turned out to be a bad battery, should have it on the dyno again this weekend for another go.
