Let me prefice this by saying I absolutely LOVE the look, and sound of the system I chose. HOWEVER, I am experiencing a lot of secondary noise that literally makes the car sound like garbage.

Under moderate/heavy acceleration I am getting the common rattle in the rear area that sounds like its coming from the spare tire section ( which is annoying but not bad by itself). I am also now experiencing a quick more noticable and loud rattle in between 3000 and 3500 RPM's that almost sounds like a BB in a coke can vigorously shaking, which sounds like it's coming from right under where the headers would be. Also the all too infmaous VQ Hiss, for me, now isnt just on decel, but also heavy accel from 3 - 6000 RPM's ( ??Exhaust Leak?? ).

All things considered, as much as it kills me, I am thinking about removing the system and going back to stock. Before I do so, I think I may take it to a shop to have it looked at to see if something wasn't done correctly on install. All of these secondary noises are seriously driving me insane! Anyone have any ideas here? Or similar occurences?

Hiss under decel. - will be there anytime you remove the cats
Hiss under accel. - means an improper install or a leak
The car is know for rattles, and mine has a rattle in the hatch while stock.
Rattle near the header area may mean a bolt was not torqued down properly

The problem with your request isn't the availability of videos, it's the availability of the videos from similar equipment (cameras) and similar tests (revs, drive-by, etc). Every camera is going to pic up the sound of the exhaust a little different. Unfortunately the only way to get a really good comparison would be to have all three setups in front of you in person.

Non Res CBE Non Res Test Pipes...

Idle with Revs, and a quick Drive by vid... Surprisingly enough, with the volume up a bit, if playing through something with nice speakers the idle with revs video is extremely close to real life. Check them out!

Is there a comparo of sound with JUST the catback? (no HFC or test pipes)
- Non-Res
- 12" Res
- 18" Res

I'm trying to decide which to order.

I will be keeping the OEM cats so just looking to compare before i pull the trigger.

Thanks all!!

There is a really good video on the Fast Intentions site 370Z page. It's of a stock cats with 12".

As previously stated, trying to compare will be difficult without the same recording device used.

Tony is great at talking you through the right system based on what you are looking for.

well he heard non res. + long tube headers last Sunday, and will probably hear 18" res. this sunday if he comes

Don't forget to check the cross brace at the rear axle... I have a piece of industrial robber in there to stop that rattle... So check your clearance there.

grr my exhaust has been stuck at customs for 2 days, i wont be getting it till friday now. damn UPS

XwChriswX · 03-28-2012, 05:41 AM

I have a rattle in the trunk as well around 2k rpms. Just can't seem to figure out exactly where/what it is. I believe it's just a interior panel reverberating against a body panel but just don't know which one it is to put something between them. It's not a defect, it's just resonance. Anyone have a similar noise and found the source so I might have an idea of where to start looking?

That's why I'm having difficulty making a choice. I love the sound these make but don't want the noise too high and with different camera's, it's tough to decide which sound I can take before I think it becomes too loud.

I have a similar noise. I removed every panel in the hatch area and it was still there. I haven tried it yet but I read that there is a counter weight on the hatch that can rattle sometimes. It's under the plastic panel on the hatch. That is one of the things on my list to check out soon.

But as of right now everything within 30 feet of my car resonates at all rpm.

Hopefully not for much longer.

i get a bit of resonance rattle at like 2500rpm but it sounds like its more under the car than my hatch. whenever i put my car on the rack for its spring oil change I'm gonna check to see if that pesky heat shield isn't bent back enough. also see if its touching anywhere else as well. i highly doubt that since it's such a perfect fitting system but i just want to know where that sound is coming from lol

I am in the same boat. I think if you are worried at all about how loud is too loud then go with the 18". I am on the fence of whether I want to go with the 12" but don't want to regret it. So if I can't find someone local to hear one in person so I can hear it inside the car as well. Then I will probably go with the 18". Then it will be HFC or TP's. Decisions Decisions.

Anyone disagree and want to talk me into going with the 12" and I won't be disappointed? I want it louder than stock with a nice sound which the FI delivers. I just don't want to have any drone while cruising around town as this is my DD. So there lies my dilemma. Anyone who has heard both in person and can comment on how much louder the 12" is over the 18" please do.
