stock z with only FI cbe will i see the full 20hp and 11tq gains or will i need to do uprev tune?

#301 Jason Z is me :D I am a member hahaha

FI did their synonym with the car completely stock except for the cbe and got those numbers, so you should see approx. the same without Uprev.

Huck, thanks for the vids!!! Man I am sooo stoked, can't wait. Sounds amazing, reps to you!!!

Thanks Z-Girl! After I get a proper tune and a few more miles on the system, I'm gonna take the car to my church and have a few different mic's with pop filters setup to do a high quality recording, and then I'll do some drive by's :tip: :excited:

I'm on tap stalk right now so I can't see your profile, where in FL are you located?

About to make my order.Im debating between CF 12" or 18". I dont want to be too loud or too quiet, and at the same time i want a nice deep bass but i heard only the SS sounds like that but i have to get Carbon Fiber

Non-resonated...

I like the sound of the 18" but I've never heard it in person. If a little drone doesn't bother you, non-resonated sounds pretty sick.

just go non res'd, if it's too loud for you then you can throw a resonator on there. But I have the CF non res'd and it's not too loud, at cruising speed it's barely louder than stock.

12" Res with either SS or CF cans. Not too loud, Not too quiet, just right. (Especially with headers) :tup:

Thought id share a compliment i got yesterday. My brother got a ride in a mcclaren and he told me mine sounded better than it! 18" w/ cf for the win!!

C'mon Chris u heard mine with all non res and how mean it was though lol pretty sure you said "it sounds so angry" lol

Never did post mine, so here it is, F.I. 18" CF CBE & HFC's all resonated:

Nice brake light :) and nice vid! congrats :tup:

Yeah, you caught me..;). I took the vid initially to find out if there was a short in the Evo light which you can see there is..lol, but revved to do the exhaust vid since I knew I needed to make one of those also..heh

I dunno, the tone was a little high to sound 'mean'. I will say it sounded Good, but not really Mean. You need to get that TT on there to deepen the tone, then it will sound Boss. :tup:

I wasn't close enough behind you to get good sounds from it on our cruise, so my vid wouldn't help you much. That's one of the reasons I'm not posting it. :shakes head:

And the other reasons? Explicit? Hahaha

Yea figured we lost the 2 guys with cameras haha

But I will say after hearing a lot of different exhaust on the Z the FI one is pretty deep compared to most which is another reason I love it.

And as for TT I'm still on the fence :(

non-res CF CBE w/ LTH's is the way to go. :driving:


:wtf2:

Yea, the two guys with camera's and radar detectors were at the back of the pack, and LEFT BEHIND! :mad: :rofl2:


The organization of the cruise wasn't up to snuff, which the way it was brought up was fine. Just we needed to get lined up outside of that park. And any road like that, you need to hit up before 10am otherwise it's too damn busy.

#540 installed and I literally could not be happier! I'm married, 45 years old and I have been walking around with this perma-grin on my face like a child. The sound is deep and throaty! Sounds so much better than the factory exhaust. The exhaust system was so well built that the installer didn't even really follow the instructions and the fitment was perfect! The tips sit exactly where the factory tips sat, perfect spacing. Seriously, this was the best purchase I've ever made!

Congrats!! Same here, 41 and walking around still after months with a grin..:)

man this is like torture. Mine is all layed out on my pool table teasing me while my car is in the shop getting all the hail damaged fixed. Its supposed to be done tomorrow then ill be putting it on right when i get her home!

I been having mine since feb and it's still just sitting with no install in sight. :shakes head:

WOW MAN Since Feb!?! lets trade!!! give me yours right now and you can wait for mines #590 CF Non-Res

I don't think you'd want to make that trade. I got mine used with about 6k miles on it, great shape but you paided for new, and it's the SS not CF cans. If you want pm me....:roflpuke2::tup:

Not to derail the thread, but has anyone had a rattling sound coming from the car after doing the headers? I put mine in, and it sounds like a little wire is slapping the pipe near the transmission on my passenger side. I took it to my buddy who manages an exhaust place and we put it over the pit, then I revved it up and he looked for it. Couldn't find anything, it was hard to pinpoint where the sound is coming from, but it's pretty loud when I'm accelerating. I looked for loose bolts, wires, heat shields, anything I could think of but I don't see anything. Anyone have this same problem?

no, only "extra" sounds we get is from the various dash/other plastic parts in the car vibrating during certain rpms.

there might be a bit of a rattling sound at startup iirc, but I think it's a normal sounds since I know for a fact everything in there is buttoned up tight and there's no loose components or anything touching anything else that should't be.

Yeah I'm gonna make a vid of it so you guys can give me your opinions, maybe I can get tony to watch it and see if he has any ideas...

kaienz34.. dood what are u waiting for. Today I got my car back from hail damage, They did an awesome job can't see any signs of hundreds of dents at all. So I got her home and me and my budddy lifted the back end on jack stands. An hour and 30 min later we had it all finished. As everyone has said its unbelievable how well made it is. fit and finish is perfect, aligned perfectly without having to adjust it one bit. The sound is better than I hoped for. I qam glad i went for the 12 inch res. The 18 might have been too quiet no res might have been a bit too loud for what I was looking for. I am extremely satisfied. I took a vid with my I phone but am not gonna post it beacuse it does not justice. Very happy #536!

I just don't have the tools, and i refuse to pay for the install. So i'm gonna wait till a good friend of mine has the time no rush. I had the stillen catback and berk HFC combo for about a year and now i'm rollin bone stock.

all you need is a few sockets bro. go buy um its so worth it. What did u think about the stillen cat back? have you heard the F.I in person what was the diff in sound?

I liked the stillen and berk combo very exotic sounding, i haven't heard the FI in person yet.

The wait begins. Ordered the non-resonated CBE with carbon fiber cans.

Any idea when your website will be back up? It's been down for well over a month if i'm not mistaken.

i was just on their site last week showing a friend my video.

The 18" res isn't that much quieter, I have the 18" and I've sat next to a Z with the 12", however, my 18" res w/ CF mufflers does have a much deeper and exotic tone than the 12" which is considerably higher pitched.
