stillen or fast intentions exhaust?
 

Which is better? I am looking at power gains and no drone.

Hands down, FI.

:iagree:

I would think majority of the forum will also agree. Phenomenal exhaust, FI makes some of the best parts for our Z.

You are stillen the early stages of membership and will find soon enough that most intend to go fast. There you go.

Smart

Do you care about noise level? Or are you interested in purely gains?

I've had both. Had a stillen, went to fast intentions because I wanted something louder. Sound-wise, I think the stillen actually sounds sweeter above 4k but overall I'm glad I made the switch to fi.

The power gains go the FI by a hair, but all exhausts will be within striking distance of each other. Drone seems to be more dependent on what you do with the stock cats, if anything. The only negative thing I've ever heard anyone say about FI is the waiting list, but that's what happens when you have the most popular product.

The stillen has proven gains, plus I always get discounts from them every time I call them up to order more parts. It isn't the loudest but defiantly IN My Opinion, cleanest sounding exhaust, 3-5k rpm's is the sweet spot.

Had a Stillen exhaust on my 08' Maxima. It was perfect for that car. I however require a louder exhaust for my Z. I do not want to have to be all up in it to hear the exhaust. I prefer the opposite in a sports car. I like to hear it just putting around.

I liked the stillen because it was a tad quieter and understated looking. If I were younger and this wasn't my DD I would have gone FI.

I have a Stillen cat back for my 09 Altima. I love how it sounds, and considered the Stillen cat back for the Z, but wasn't a huge fan of how they kept the stock style Y pipe instead of keeping it as two pipes (which I believe the NISMO Z's already have) and I personally don't care for the tips they put on it.. looks too 350Z-esque to me :wtf2:. I have heard the Stillen cat back on a 370Z though and it does sound nice.

I've got a Fast Intentions exhaust on order :tup:

yes i do care about the noise level. i don't like the loud drone on long drives.

nono I meant the actual noise level aside from the drone/rasp. That was my deciding factor to not getting some of the other exhausts on the market was the excessive noise.

Figure out what you're going to do with the stock cats first. An exhaust that's "just right" with stock cats may be too loud, raspy or drony with HFCs. Test pipes even worse. Plan out your whole build before you start ordering parts unless you want to find out that you bought the wrong exhaust for your desired noise level.

the noise level i don't mind too much, it is the drone inside the car that i am concerned about.

and i am keeping my factory cats

Go with 18" resonators and you won't have any issues. Especially on the stock cats

If your keeping your stock cats,than your not overly concerned about power gains,just a change in sound. If that's the case,you might be better off just finding some axel backs. Save a bit of money and you don't have to wait for the exhaust to be made.
Anybody know the muffler brand that fi exhaust comes with?

i have the stillen on my Z and i don't regret getting it, but i also wasn't looking for a loud exhaust.

If you're gonna drop money on an exhaust.... Why not make it known:tup:


370Z exhaust system FI carbon fibre CRAZY NOTES!!!!

We have installed a bunch of both and have never had a customer say a bad thing about either. Both bolt up with no problems with great fitment.

If you require a more mellow and lower volume overall the Stillen may fit the bill for you.
If you are OK with a higher volume and a little more raw sound than the FI will be perfect.

Thanks all for the replies guys

I have the FI w/ 18" resonators...LOVE it!

Get nothing but compliments on how it sounds, adds decent power.
Super high quality product.
