Smoke24,

Thanks again for your time and your business.

Go 18" if it's your everyday drive car less cabin noise below 3500 rpm you will bot lose the full noise effect. I got my FI 12" love it but yes noise cabin is a bit louder "not cool for hands free call lol" but as far as FI all over sound and quality..they are simply the best in my book..

My case, I took my car to the dyno (DynoJet) with just the Stillen Gen 3 CAI and stock exhaust and got 295whp. When I got Fast Intentions non res HFC with 12" res CBE on the same dyno, I got 322whp with Uprev tune.

That's very nice. I'm on the FI waiting list :( between April - May time frame. I also have a Stillen G3 CAI on the way next Monday. I went with the FI CBE 18" res and FI non res HFC.

Just out of curiosity how do you like the sound on your setup. Too loud or quiet, any rasp? What WHP did you get before the uprev tune?

Thanks

To add on what Kevin said and touch on what you want...

Personally, I am a big fan of our non resonated X Pipe with stock cats. It is such an exotic sounding exhaust note. Very "Euro" so to speak, however no rasp and very clean. As Kevin stated, the resonators with smoothen out the exhaust note and create depth along with quieting the interior cabin noise. They will "slightly" quiet the overall note down from the outside the car but the main effect is interior.

In terms of having it quiet inside the car and loud outside the car, that is a tall task for this car. As we all know, the noise canceling material lacks from the factory and the high amount of road noise stock is something to frown upon. BTW, it's not much better in the GTR! The 18" resonators are your best bet to keep the interior noise to a minimum and believe me, you will still here that exotic and smooth exhaust note from outside the car.

If you have any questions at all, please do not hesitate to give us a call.

Thanks.

Tony, we should just start pointing people in the direction of the "FP Option" :stirthepot:

but to add onto Tony's original point but the non-res set-up on the FI exhaust is amazing. my original set-up was non-res CBE and non-res TP which is a bit much for most but the sound Tony's exhaust makes in any of it's variations is just perfect. the fact that there is so many options to mix and match, just gives any customer the opportunity to create their own perfect set-up.

For me personally the louder the better, but I'm happy with my set-up. When you floor it you'll hear it trust me, but cruising on highway you barely hear it. In my case I have no tin can rasp, just a nice deep growl. I didn't do a baseline on whp, but like I said, with just the Stillen CAI and stock exhaust without a tune I got 295whp, so I'm guessing my car all stock would have been in the 280-270 high whp.

Went with test pipes and 18" resonators with 100 cell hfc integrated to the Y pipes and it put a smile on my face every time. Amazing sound.

Considering you have to take the doors apart to apply dynamat to the whole car, wouldn't that produce rattling and be counterproductive?

I'm tempted to do this myself, but am not so sure about the doors - last time I had a door taken apart to re-paint a car, it never sounded the same again :-\

Non-resonated are not that bad. You can't beat the sound up in the RPM range 5500 and up. I can still listen to the radio and talk on the phone with no issues cruising at 78mph on the interstate. It's a little loud at first but not bad at all. You really have to be in it hard for them to be loud.

Yes, I have stock cats.

... at least, not when you're driving a Z :tup: :inoutroflpuke:

Seriously though, my 18" resonators and resonated HFC's are still loud and deeply throaty that my GF used to tell me that the pictures at the back of the house would shake when I cranked her up in the morning. However, I could still hear my radio, use my bluetooth, and not get a headache from the drone on long trips... and when I downshift or hit the gas, the sound was/is a deep throaty growl that intimidate the car infront of me, so much so, that some actually pull over to let me pass. .. figure they had to go home and change their underwear afterwards :icon17:. I have also been told from other non-Z friends driving behind me on trips that I sound like a Ferrari. .. smooth, silky, growly, no drone, and no rasp... perfection incarnate. .. well worth the price and wait. Heh, I could do a commercial for FI...:rofl2:
