If you are concerned with "loudness" at all I think you would want an 18''. Best bet is to call Tony there and he will give you a loudness test to figure out what would be best for you.

I ended up getting an Ark Grip used (which I love btw.. silent @ cruising speed, and very low rumble @ idle, and growls when accelerating).. but I would of gotten a FI if I had not come across a decent deal.

That sounds like about what I want. I do a lot of 30-50mph speeds because I live very close to work and school.

I just feel like I should be able to handle 12" if people are getting non res and are content with it. But I don't know

I guess talking to him would help a lot. And ultimately you only know for if you get to hear it in person haha

Either way its going to be louder then stock.

I think the 18" just gets under the 85 decibel law.

I picked up a used FI exhaust, SS with 18" resonators, from a member on here and had it installed today. After reading through this thread, I fully expected it to not be loud enough and to plan on getting HFCs to up the volume a little. I was wrong. I wanted an exhaust that not only sounded great, but wasn't obnoxious when driving at lower speeds through my neighborhood, had a nice noticeable volume response even when just lightly applying throttle, and could scream above 5000rpm. This exhaust does it all for me. My point is that...compared to stock...the 18" is neither tame nor quiet.

I could certainly be happy with 12" resonators and get along fine without annoying the neighbors. To be honest, as I get used to it, I might want to increase the volume a little bit at some point. But if you're worried about it being too loud, then I don't think you would be disappointed going with either 18" or 12". The 18" is a very noticeable upgrade from stock. Personally, I don't think non-res would've been a good fit for me. I'm not getting drone in the cabin and the volume of the exhaust comes through just enough to replace the usual road noise I hear. The road noise was annoying...this exhaust note is not. Net positive there.

I have 12" res. and love them. At idle after warm up is fairly quiet. A little louder at cold start. At low rpm it's not that loud but has a nice deep tone. In the 4k-6k range is the sweet spot to me. Loud but not crazy loud. Up around redline, I don't really hear just the exhaust, everything is screaming... Hope it helps some. Have you listened to the different options on youtube? It's not like in person, but it helped me decided. Tony is also helpful with helping you decide.
You can't go wrong with any of the options, it's a beautiful system in all ways.

911 here. Now you have me excited lol. :excited:

I'm going through the same thing as far as deciding on non-res, 12" or 18" however I will be pairing whatever type I get with the FI LTH's. I've been leaning towards getting the 18" but I guess I should probably talk to those who also have the FI LTH's.

I'll be ordering within the next week or two so I will need to come to a decision pretty quickly.

921! Getting closer.. I went with cfe and 18'S

I've put on some SS mufflers this time on my car, here's what it sounds like after break in:

Pure sex

Thanks that helps a ton. I will also eventually sound proof my car a bit when I upgrade the stereo so that would probably block some of the sound.

And if it is a little too loud for people outside. So be it haha

I love it when sparks fly at 1:17 and 1:23.

sparks...or FLAMES?!


sounds great

Flames, wow. Is that normal?

Test pipes, hfc's, headers, Yes.

My old vette used to spit 12" flames, straight 3" pipes motor to tips no mufflers.

I am not going there.

:happydance: My weekend has started! And I'm getting the exhaust installed in 3 days!

So jealous of you right now haha

well if Genesis is getting it soon, that means we're around 906... I guess I have 11 more people in front of me! Looking back, those last 5 weeks sure did pass by fast! Hope you get the E-mail soon Gene! so there'll be one less person in front of me!:P

^^
I am 906. I'm driving out to FI for an install this Monday so I won't recieve an email :)

920 here, I am just trying not to think about. But I still find myself checking this thread twice a day. I also visit the FI site daily to look at pictures. It's hard not to think about it when I am always thinking about it.

Hahahaha I'm 931 and I'm in the same boat as you I'm just so excited for it

you only check this thread twice a day??? I guess I should cut back on checking this thread every 10 minutes!

Sam has an RB30 Turbo in that thing!!

It's stock man, just some bolt ons :p

Wow, I don't know about you guys, but I have a FI CBE, w/ non-resonated SS cans. Tony said I'd lose ~8-10% sound, after breaking in/ECU rerest. Have to say, car actually sounds exotic, sound is perfect. I like sound, so if you're looking for quiet, maybe this isn't for you. This pretty much is the best sounding car, I've ever had, and it's BC of the FI. Had a bunch of muscle cars, this ones sweet...happy motorring MHLivesay

I haven't the slightest idea what number I am....

you're 923, so you're right after me :P

I will second that I get so many compliments about the exhaust especially at the track when you can really get on it. Young guys old guys it doesn't matter when it sounds badass it sounds badass period.:tup:

Now how did you figure THAT out??

Go to page 234 post 3507, Tony posted an updated order list. Also you can find out your order # from the PO # on the invoice he sent you, they are one in the same. :tup:

Thank you, I had never noticed the PO number on the order...and would have never found that list!

Tracy Ramsey

No worries Tracy.

Yes!!! I'll be waking up at 600 hrs to make the 1-2 hr drive to FI first thing in the morning!!! The day has come!:excited::excited::excited:

Exciting time! You will lose your mind on the first cold start :)

Even SpecialtyZ has to wait with everyone else, Seb has 3 still on the list!!
