FI Non res vs resonated CBE

FI CBE exhaust non-resonated here with stock cats. It sounds excellent with the SS mufflers. Drone is not bad at 3K rpm. Exhaust note is not an issue talking on

FI CBE exhaust non-resonated here with stock cats. It sounds excellent with the SS mufflers. Drone is not bad at 3K rpm. Exhaust note is not an issue talking on the phone. The car is just noisy by nature. Get on it, and it will scream a beautiful sound in the upper rpms.

I'm now watching a lot of 12" and 18" resonator vids on YT. Some people are swearing by the 18", but the interior noise is too close call between the two. The only thing that's bugging me is how low those rear mufflers sit. I actually paused and took a screenshot to compare it with the stock system. The last thing I would want is to bang them up on a speed bump or getting off the road into the office driveway. As it is, that black f/bumper guard touches abit if I don't enter at a wide enough angle. Still stock height, not planning on lowering.

I found this pic on the forum.

http://www.the370z.com/attachments/i...s-img_2356.jpg

That phone is 4.2 inches high (Blackberry Pearl). So i'm guessing the lowest point of the exhaust system is 4.5 inches high (11.5 centimeters). Can anyone confirm this?

The lowest point (Where the phone is in the picture) is as low as the stock exhaust system is at its lowest.

If you need any certain pics/vids let me know, I am in the process of compiling all the ones I have taken (I have FI Nonres CF).

Not to someone that doesn't want unburnt fuel smell in their cab. I don't have a CAT anywhere in the system and my car smells like an outboard motor

OP. I love my non-res FI exhaust. No drone what so ever but I also have a turbo acting as a hell of a muffler.

FPEnvy, that 3:07 video was one of the first I watched when I started looking at CBE systems, I thought you did an engine swop at first

I've decided on resonated. Just matter of 12 vs 18. It's a $30 difference, so that's fine. Was seriously considering the 18, because people say that it's close to stock on the interior but I do want more volume when I drop the hammer. decisions decisions...

no engine swap just exhaust swap lol

if you want the least drone and interior noise then go 18"

me I could care less about it. its a sports car and should sound like one to me lol

I don't mind a little drone. For my eargasms, i welcome it. But if it starts causing more stuff to rattle, squeak, creak. Especially in that soft top, then I'll go 18". Wonder if there was ever a poll done 12" vs 18"?

Honestly. It all depends on how sensitive your ears are along with how much "noise" you're looking for in terms of Exhaust sounds. When I bought the NR CF i had only heard a 12" Res + NR HFC in person, and I couldnt stand the added "hiss". And it was a DEEP sound. I would say 12" is the perfect midpoint for Loud (when on throttle) and quiet when cruising. Just know in colder temps (50Fs and lower + cold starts) will be even louder.

I'll post a vid from inside the car later tonight (again it'll be NR CF).

CF = Higher pitch 3K Rpms+
SS = Deep = Entire Rev Band

So I tried, something new to compare the sound difference from stock and other exhaust systems. I recorded my car on hard pulls, cold starts, warm starts, normal driving just to hear what it sounds like after being recorded. Then comparing those sounds to the YT vids helps me better understand the difference. I mailed Kevin @ FI. Just waiting his response.

It's really hard to judge audio differences from a vid. All I can attest to is that it sounds plenty loud (in a good way) with the 18" resonators. If you want it as loud as possible, then go with non-resonated or 12". I was leery of anything less than 18" because I wanted to minimize the likelihood of buyer's remorse. I was looking for better sound (wanted to get rid of the vacuum-cleaner-with-a-clogged-hose stock sound) not necessarily louder. That said, it is plenty louder than stock even with 18's and sounds like a beast. I doubt I would want any louder. So, it really depends on what you're trying to accomplish.

The cans sure look lower than stock, but I think its an illusion. I go over speed bumps very slowly and try not to drive too fast on a rough road where you can bounce around and bottom out. These cars look really cool lowered, but my nerves could never stand it. To many uneven roads in my area.

ReeceZ, I just posted 3 videos on YouTube that can help you decipher the difference between stock exhaust and non-res SS. Hope they help:
