Has anyone weighed one of these exhausts?

edub370 · 03-25-2012, 03:17 PM

sure haven't. never really thought to do it before i put mine on

Bandit_Kaine · 08-11-2012, 12:38 PM

anyone here still running this?

Does it drone at all in any rpm?

Can you compare how loud it is to say stock?

i'm running AAM short tails but it just drones too much at 4k rpm and its way to loud.

I am still running it. Doesn't drone with stock cats. The sound isn't that loud after breaking in. Just a tad louder than the Nismo exhaust. If you want louder, should go for another exhaust. Or get this setup with test pipes. Then you will probably have drone with the tests.

I used to have this with ART pipes and it wasn't loud and didn't drone.

If it weren't for the fact that the fit was pretty awful I might have maybe kept it. Although I wasn't a huge fan of the sound it made. It just seemed a little flat, didn't carry any sorta distinguishable tone.

a couple laps of me driving Daisuke's 370 on the AMS Roval course

edub370 · 08-11-2012, 05:51 PM

Still no drone with test pipes. My vid has test pipes on it.

I think this thread is worth bringing back to life!

Just curious, I will only have this as intake/exhaust mod for now, I keep reading it's not much louder than stock just deeper. few questions:

1. how long are the resonators? 14"? 18"?
2. piping diameter is 60mm according to the first post. that's 2.36". Do other exhaust brands have the same diameter and just round the number to 2.5" for marketing purposes? I'm guessing difference could result in possible lower gain. but then again, I know, wider isn't always better.
3. Does any company provide pre-fabricated straight-pipe/X-pipe mid section replacement over the resonated pipes in this system? there is always the "custom" route but I'm just wondering

zefaulter · 05-18-2013, 03:04 PM

Ok I have answers to couple of my questions.
Resonators are 14". For the most part, pipes are 2.5" except flex pipe inlets. Those are 2.36"=60mm
Car sounds slightly lower than stock but way deeper. Still haven't driven the car yet. Install was super easy, so far no leaks

Gibby1113 · 05-19-2013, 02:28 AM

Any dynos so far? What kind of power does this exhaust add??

SATX_NISMO · 05-21-2013, 02:33 PM

Anyone know for sure if this CB will fit a Nismo? Web site says it will not.

No dynos yet I believe. I did a pretty long search once for them.

Happy with their test pipes so far. Would probably get this if dyno results were significantly better than stock.

chrischhorn · 05-23-2013, 10:32 PM

I did a dyno but the dyno times were so far apart they kinda dont work. Originally my car did 276 whp. With the CNT it did 287whp but no power was made until after 6700rpms. BUT the thing is, original dyno was done in March at around 50-60 degree temps. CNT exhaust was done in July which was dead in the center of summer in TEXAS. 100 degrees easy. The only downfall to this exhaust is the weight. Its probably about the same weight as OEM. Quality is decent but over a long period of time I could probably see issues. Fitment was kinda bleh for me. Most people had no issues.

zefaulter · 05-26-2013, 08:46 AM

I'm thinking about getting a exhaust shop build 2 pipes so I can replace the 2 Resonators. It'll be a direct fit/replacement, no chopping necessary. for days I want to have a louder exhaust... Any comments?

Louder is better, but removing the resonators may not be the best as choice as they usually help in filtering out rasp and drone.
