Would love to hear this exhaust with Berk HFC's and the 18" resonators option.

Or FI's HFC's...

I agree, my order is power/sound/price, but what I hope to see with most exhaust systems is you can get anyone and the difference will be +/-5WHP. Then it just leaves it to sound for me, but I have high hopes most of the time.

^ videos are only a so-so indication of sound - you really have to hear it in person...

I considered the 18" res but I'm affraid that should I remove the HFC's for whatever reason down the road I'll wish I had the 12" one with the stock cats.

Tony, when you recommended the 18" with HFC, do you feel like there would be a HUGE difference between the two (compared to 12")? Is it a matter of pitch/tone/volume or would it reduce rasp?

Also, as I said I'm ready to purchase today and would be more than happy to pair the combo and record video, write a review, etc. If you would like, PM me a price shipped to 40509.

When do you approximate the initial sales will be built/shipped? (if I were to pay you now)

As Tony already said, they're well established enough and their previous applications all showed nice gains that I feel confident in this system, even before seeing dynos. Also, as someone else pointed out, for me, a few HP (5-10) on a dyno will more than likely go unnoticed to me daily driving, however I will listen to her purr every time I'm behind the wheel. That being said, to a point, I'm willing to place sound/looks over power when we're talking on a small scale such as gains between catback exhaust systems.

Well put!

The FI exhaust on my sedan uses "only" 2.25 pipes and already gets 9 WHp averaged over 3 pulls each. The pipes were changed with the car on the dyno so the pulls are good. Still works great with forced induction as well.;)

You guys will definitely get good before/after power comparisons.

Dreamer whats up, As soon as I install it Ill cruise on over to run it side by side with your car. As far as the HFC's go I took Tony's advice to test out the catback with the 18 inch resonsators first. After which I may go ahead and swap out the cats. These of course will be also Fast Intentions. My ship date is close to the end of the month.

You probably CAN get any one of them and be neck in neck with power output, but the only way to really know is to have an independent 3rd party do 3 baseline dynos, install exhaust #1, do 3 dyno runs, install exhaust #2 and do 3 dyno runs.

As many forum threads have stated, a typical exhuast hp gain on the vq37vhr is less than 10 hp from aftermarket exhaust alone. When a competitor claims 20 hp gain and your product is only showing showing 7 hp gain on your dyno, it gives you a lot of incentive to fudge numbers so that your exhaust setup looks as good as the competition. Its easy to do. You can change the calibration on your dyno, telling it that it is at a different altitude than it really is. You can do your "before" dyno runs during the hot part of the day so the hp on the car is down, you could add a little 100 octane to the tank, you can change how much cold air is directed to the front of the car from fans, etc. If you want the dyno software to print all that info, it can. A lot of tuners don't want it on the dyno printout because then you can figure out where they fudged the numbers.

The only way to compare the Fast Intentions exahaust to Stillen or any other manufacturer accurately is to run it on the same car, on the same dyno, at the same humidity, temperature and barometric pressure. Otherwise the numbers are not truely valid.

Since the above scenario is not likely going to happen, I would buy the exhaust based on sound preference, just knowing that there's not going to be much difference between competitor #1 and #2 in terms of performance.

One thing I noticed in a few clips in the exhaust sound/video clip thread is there are a couple that have the "rattle can" thing going on.

I can't stand that in my exhaust as it makes me think something is wrong.

Stillen/Berk is one that it popped up with someone driving and it's a turn off, which, given that was my best previous choice, I have to ask - does this one have that rattle-can sound at any RPM?

I think that was an issue of part of the exhaust not clearing a suspension component. The result was a metal on metal rattle. I know Berk said they worked around this and Stillen exhausts required some fiddling around on the install.

Wow now the guys at the370Z are getting some FI love too eh? haha that's one mean sounding exhaust, went for it on my G37 and never looked back lol

Ground clearance of the mufflers shouldn't be a big issue since they're aligned nicely with the wheels meaning they'll move up and down with the wheels as you go over speed bumps. Of course, you still need to drive carefully with a drop, angle in, angle out etc..

Those of you curious on how it sounded on my G (since we pretty much have the same engine) can check out the video's I recorded a while back

He sure left a satisfied customer in Dubai and to that I owe him those vids haha, keep up the great work Tony :)

Dude that sounds awesome with the test pipes! :tup::tup::tup:

Sounds like the FI exhaust + test pipes have ALOT LESS rasp/high pitch rattle in that 2.5-3k range compared to others systems...Looks very well built too!

Thanks Steve, forces me to keep the radio off sometimes haha
