I just got my Fast Intentions exhaust installed on my 370 this past week and it sounds great! I made a little sound comparison video so you can hear the difference.

 

Holy smokes, that sounds badass. Don't change anything else!

 

Great vid! Sounds and looks really good!

 

Nice vid, you even replicated the shift points.

 

Thanks guys! We spent a lot of time shooting. We did multiple takes of every pass and angle so I could be sure to match everything up perfectly. I wish there were more exhaust videos like this. It's usually so hard to tell how the sound is going to change if you don't have a before and after clip.

 

Was this still with the stock cats? Or were those changed out as well when you installed the Fast Intentions exhaust?

 

The stock cats are still on in this video. I plan on doing the resonated HFCs next. I'll probably have a new video once I get them installed.

 

 

Perfect video, sounds awesome man.

 

Sounds great!
If it were me,I'd leave it the way it is.However,if you want more of a "snarl",go with
The HFC'S
Fast Intentions makes great stuff.
If add HFC's,resonated or,non resonated,it will be louder and have more of
a rough edge compared to what your video showed.All HFC's will have a bit of
a rasp.But,hey...thats ok by me.What other mods have you done to your Z in the way
intake etc?Suggest a tune (unless you already have this in the works)after your
HFC's are installed.A big plus from a tune will be to modify your throttle opening.
The system now is graduated.A tune will allow WOT.When you hit the gas,it will
sound brutal!

 

Oh, I didn't realize the HFCs would add rasp? You think I'd get rasp even with the resonated HFCs?

I'm about to do an intake (Stillen G3) and then do an UpRev tune on it. I wanted to wait on the tune until I have most of my mods done. The closest UpRev dyno tune is 200 miles away.

 

sounds really good
