CBE Replacement Summary
 

Hey Everyone,

I, like many of you out there feel that the 370z Stock Exhaust is too plain. So I began the quest to see what CBE replacement exhaust would fit my personal taste.

I know there have been many threads started about exhaust replacement, but I wanted to contribute the forum with the research that I found.

My criteria:

1. Tasteful Sound ( mildy exotic, not overly loud)
2. Performance
3. Asthetics - I want a nice fit to the rear fascia
4. Price - (I always want good value)

I compiled all of my research that met this criteria into a matrix so I could evaluate all of it at the same time. I evaluated (sound / performance / asthetics / PIA factor / cost plus other little details). I have embedded hyperlinks to You-tube videos for various driving sounds of each system.

In the end there were 4 systems that I seriously considered.

I also want to mention that I am no expert on the matter, all of this information was pulled from various sources. Pricing provided was from Forum sponsored vendors.

If you find this information helpful then help a brother out with his rep power.

Cheers.

F.I. exhaust seems to meet all your criteria, not sure if you like it Aesthetically. But this forum loves the FI exhaust, so I'm sure that's where all the recommendations will go towards. I personally wanted to go for the Tanabe exhaust+Y-pipe, but not a lot of people went with that exhaust.

On a side note... what do you do for a living (the exhaust matrix makes me wonder lol)?

I ended up chosing the Tanabe exhaust. I love F.I, but the drone was not for me.
I'm an engineer - is it obivous.

addition: Invidia Gemini has an X-pipe.

Nice, Tanabe is a great choice. Shop around with vendors, the quote I got for it is a lot less than what you have listed, with the Y-pipe.

And yes, very obvious... how many exhaust choice worksheets do you see on here?

Thanks for the feedback.
That is why I thought to helpful to compile everything all in one place.

ur too organized to be an engineer.

I purchased the Tanabe cbe for $1050 shipped and the Cheap Y pipe thread for $80 shipped.

Nice compliation of relevant info -- but I would consider reporting the gains in terms of % increase from baseline; even on the dynojet, the raw value gains will be misleading, given that they may all have different starting values.

If any data are from another kind of dynamometer, it will be impossible to comare and contrast without considering % gain rather than raw value gain.

You defiantly wouldn't want my setup then. But it's what I love. Damn I love these cars.

How was the fit between the Y-Pipe(Sure-win) to the Tanabe system. Any difference in sound?
That is a good price on the tanabe system. Where you dealing with a forum vendor?
I will still probably stick with the overpriced Tanabe Y-Pipe.

A real engineer would draw graphs with error bars, etc. :stirthepot:

Yep Also interested in where you got it!

A real engineer would make his own exhaust :stirthepot:

What kind of engineer are you? I'm a chemical engineering student at the moment.

I installed the Tanabe and the cheap Y pipe at the same time. Fit was fine. The thing I did not like was outlet of the cheap Y pipe, 3 inch, did not match the 2.75 inch inlet of the Tanabe CBE mid section. The vendor was not a forum vendor. PM me if you need more info.

PM for info.

I'm torn between the Invidia and the Tanabe, but without the decibal ratings, the Tanabe wins out.
I've got a price of about $1180 for the Tanabe (w/o the y pipe).
If anybody knows of anything better, I'd love to hear about it.

You will find with experience, there are some things you make and some you buy.

I'm a Mech Eng.

Yes, I might.
After I purchase the exhaust, I will run a computional fluid dynamics simulation to see if the theoritcal gains much the dyno-tested results.
:icon14:
jk of course
