Fast Intentions exhaust is here!

Togo · 07-06-2009, 08:12 PM

What I want to know is why do they recomend the 18" resonators with HFCs but 12" resonators if stock cats? Is it because with the HFCs the exhaust might be too loud or is it related to Rasp?

G37Sam - Those vids sounded amazing. I love the way this thing sounds!

I pulled the trigger and ordered this exhaust for my 370Z. I ordered the carbon fiber mufflers version (6 lbs. lighter than regular mufflers), and I have Berk HFC's sitting here that will be installed the same time as the exhaust. I am confident that this exhaust will have good power gains. 2.5 inch diameter piping, good x-pipe design, and the mufflers go straight out instead of the stacked design that has more bends. I anxiously await the arrival of my new exhaust.

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

YouTube - Fast Intentions Non Resonated Test Pipes

YouTube - G37 Resonated Test Pipes + FI Catback Revving

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

Hey there he is, Sam.

My Middle Eastern exhaust distributor. I am glad you chimed in buddy. It is always nice to hear from you. BTW, the Sedan system for your friend should be in the mail by Friday...

Thanks, Tony

IMO, the non resonated test pipes did introduce a little rasp down the road which I didn't like, and became (police magnet) loud lol. That was why I fitted resonaters in them later on.

It is a different story with HFC's though, I'd say it has to do with it becoming very loud and not a rasp issue.

You hit the nail right on the head! Thanks for the order #002

G37Sam · 07-06-2009, 08:22 PM

Good call with the CF mufflers, they do look insane from behind haha

Ask and you shall recieve...

The reason we recommend the 18" resonators has nothing to do with rasp. It has to do with interior noise resonance AKA: Drone!

The longer resonator will not hurt performance. It will not change the pitch. Well, I lied it might make it deeper with more of a rumble. I personally think it will sound great with HFC's!

The point is to achieve the optimum sound without driving you crazy inside the car. I also like to give you all options. Options are good as people are different and like different things. But, don't worry about rasp. That will not be an issue.

haha that's good news Tony!

Togo · 07-06-2009, 08:28 PM

Wow, thanks for the prompt response. That answered that completely. I was wondering if it would change the pitch at all but if it just gets deeper, then great! You can't go wrong with that. I think a lot of people will run HFCs so thats a good bit of info right there.

On a side note, does anyone have some close up shots with the CF can?

m4a1mustang · 07-06-2009, 08:30 PM

What size are the resonators in the video? 12" ?

I think I'd want to go with HFCs in the future, but I'm not 100% sure... so I wouldn't know which exhaust I should order...

I demand videos!

bullitt5897 · 07-06-2009, 08:32 PM

Tony will there be a burnt tip option?

G37Sam · 07-06-2009, 08:53 PM

I believe Tony mentioned earlier on in this thread that the current setups come with 4.5" tips, the burnt Ti tips come in 4" but are not available yet for the 370Z, maybe later on down the road

12" in the video.

As an option, if you wanted to you could buy the system now with 18" resonators.

Then if you decide down the road to install high flow cats and you feel the system is too quiet, all you need to do is purchase is the center X Pipe section with the smaller resonators. I know, I know, it is more money however it just gives you options. Feel free to call me if you like...

Thanks, Tony

Thanks Tony. I think I'm just going to give it some time for members to put up videos so I can identify my ideal setup. I probably will not be doing anymore mods to the car until the September time-frame (my Birthday... therefore the SO is more inclined to let me do stuff I want to do

).
