If you're doing FI catback does G3 make a difference?

ped · 09-16-2013, 08:18 PM

I'm about to get a Fast Intentions catback with either a 12" or 18" resonator installed (staying stock cats for now). Is it worth it to also do the Stillen G3 (Gen3) intake mod at the same time? Will I see a benefit there? How about maintenance? Is there anything you have to do to the Gen3's filters? Is there a worry about them getting wet?

You will see a huge difference and I highly recommend it !

Thanks for the input! Know about whether water is a concern? How about maintenance?

Check engine lights aren't an issue?

How about the ECU? Does it deal with both a catback and a G3 without a tune or is it best to get it tuned as well (adding how much $ to the equation)?

I put down 301/245 SAE w/ just those two mods. I say go for it!

edit: I had CEL, when I reset the ecu using the "pedal method". I then reset it by unplugging the battery and it never came back.

I would highly suggest purchasing then Gen3. Every 370Z that I have tuned makes more power on those than any other intake. The maintenance is not that bad as they do not seem to get that dirty. I wouldn't worry about getting them wet(that would mean your driving the vehicle on flooded roads).

As many threads have said, you don't need a tune. It's better if you get one, but its not a requirement.

Leuz · 09-17-2013, 02:10 PM

+1 for the Gen3. If you get a tune too you can make some nice power.

Lothario · 09-17-2013, 02:21 PM

i did FI CBE w/ 12" and g3's... no error code, great sound, more pep... go for it.

ped · 09-17-2013, 02:47 PM

Ok I did both the FI catback and the Stillen Gen3! Picking it up after work today...

Its best to tune with your final 3rd breather mod (HFC). The way the filers sit you would need to drive your car into a lake. If your installing yourself careful when it comes to your ac lines and use hose to cover them or pay the price later down the road. Wow big changes about to happen to your Z. Congrats.

ped · 09-17-2013, 08:27 PM

Well I can already tell it's faster after a 30 mile ride home and a couple of stoplight runs. But damn is it loud. I got the quiestest setup there is, right? Stock cats, with 18" resonators. I'm almost worried this is too loud and annoying. Does it get quieter or do you just get used to it?

It's the quietest Fast Intentions option yes, some people find it loud some find it too quiet, you are in the first group

And no, it won't really get quieter. If it's bothering you too much, you can consider the Stillen cat-back, which is considered to be quieter, but of course it always depends on your level of acceptance. I doubt you'd find an aftermarket CBE as quiet as stock tho.

When I first installed my Fast Intentions exhaust, I also thought it was too loud. But after a couple hundred miles of break-in time, it actually quieted down a lot. It was a very noticeable change. Now its actually a bit too quiet for me. Go figure. I may end up giving Tony a call to order a different x-pipe (12" or non-res).

Overall, I'd recommend giving your exhaust some time to break-in. It just might settle into a tone that's perfect for you. If after break-in you're still not happy with the sound, you can also try upshifting/downshifting as necessary to get out of the RPM range where droning occurs.

ped · 09-17-2013, 10:16 PM

That's what I had seen in other threads, that it does get quieter. That's a good thing as I'm liking the power increase. I'll see how it does over the next couple hundred miles.

Hey guys don't mean to Hijack the thread but I have a quick question...

I have the FI 18" Res & AFE Drop Ins with Z1 MAF Tubes...

What would you do next (more bang for the buck):

HFC or G3 Intake?
