Love the craftsmanship...excellent quality....great customer service. The carbon fiber canisters r jus gorgeous. I lov how they r almost undetectable on my black Z. But its jus 2 loud for my taste...

Did you get resonators?

I'm sorry to repeat my question, but my exhaust is just a few weeks away... does anybody have any idea how many rwhp the FI exhaust will net me over the factory Nismo exhaust? No way it's a downgrade power-wise, right? I guess it's too late anyway, but I'm surprised nobody has been able to quantify this. Come to think of it, I'm surprised I didn't do this homework beforehand.

Probably around 10-15, maybe up to 20 whp over the Nismo. (that only applies if you have a bone stock 370Z Nismo)

Honestly, it's hard to say exactly. The difference is probably very minimal. Most exhausts are going to give you a very similar power increase. You're probably talking 2 to 5 rwhp difference between the FI and the Nismo, at the most. It's most certainly not 10 to 20.

Unless you're going with forced induction at some point, your choice of exhaust should be based more on build quality and sound.

/my 2 cents

Bone stock 282 HP and 230 Tor on a Mustang dyno. 320 HP and 269 Tor.with LTH's, 12" Res, Stillen G3 cai, and a UpRev tune on a DynoJet.

Haha, hmm... I know you've told me that before, but hard to parse out how much is the exhaust and how much is the LTHs, G3s, and tune.

I plan to do the tune eventually, but will probably keep the stock intakes w/ post-MAF tubes and drop in filters... and already have HFCs; probably won't do the LTHs. I've heard horror stories about the install.

The driver side is a PITA! Drop the exhaust from the cats back took about 45 minutes. The right side header took about 1 and a half the drop the cat and factory manifold together, and install the FI header. The left side took about 5 hrs overall. The factory heat shield is what makes it hard. Only 3 bolts hold it on. Once you get them off. You have to turn/twist the heat shield upside down to remove it. That took about 3hrs to figure it out on how to do it. Once I got that out of the way. The factory manifold and cat was out in an hour. The FI header took about an hour to install. Now if I do it again. I could cut that time by half.

Then I should be happy with mine. Non-resonated carbon fiber......5 weeks out. Feels like eternity. Will get HFC once my warranty expires. To be installed where all great exhausts come from. His shop is 5 minutes from where I work. The perks of living in SoCal......aside from the great weather of course.

Sounds like you're one of the few who are not convincingly and entirely happy with it because of volume. If you have the 18" res then that's pretty much the end of the road. The compliments you get will probably change your opinion but if you decide this is not for you, you could still sell it and then get a Motordyne

The sound will settle down quite a bit after you put a few miles on the system (a few hundred miles), especially when warmed up. I have the 18" Resonated CBE and Resonated High Flow Cats (all FI), but still, at cold start-up it shakes the whole house and I'm sure my neighbors can hear it nice and loud... however, once the RPM's drop (30 seconds later?) the sound is still deep and rumbly but a lot less noisy. I usually do creep out of my subdivision in first gear at low rpm's to keep the noise down. Once warmed up though, the exhaust is at a perfect note: at idle, you can just hear the deep rumble, but when I put my foot in it, it sounds ."..like a Ferrarri..." (I'm told - not making this up!). So, my advice is - be patient, it'll get there. Now a small caveat: not sure about the Carbon Canisters if they are louder than the stainless, but I'm sure that there shouldn't be that much dffference. Are you still on your stock cats by the way?

Hey! I'm syoll on my stock cats and plan 2 stick with them lol. But i think u were right...either i hav gotten use 2 the sound or they hav "calmed down" a bit

i love the throaty sound. Well worth every penny! I plan 2 get it realigned 2morrow so the canisters r even. Thanks bunches for ur input! I soooo luv my Z...it sits jus right and sounds jus right!

Question on the FI CBE. I have the SS 18" Res on order with HFC's. If I decided down the road to go 12" res or non-res, how much hassle is it? Curious on what would need to be replaced.

Thanks!

Tony explained to me that it is easier going from Non-res to 12 to 18 because you just have to cut out material & put the resonators in. The reverse of that is going to cause someone to weld in extentions to the pipes. It will not look as clean either due to the patch work.

Darn. Thanks for the reply. Anyone else have a better answer I would like more?

Anyone have the SS 18" or 12" Res in the Roswell, GA area? I would love to hear it if possible..

Nobody at the local show had it
