what is the diameter of the new pipe? isn't stock 2.25?

 

Is it just me or does this look almost identical to the Nismo y-pipe?

Great gains

 

actually it is identical to Fujitsubo, which is one of the best y pipes out there, they did a very nice job indeed..

 

i think im down for one. as long as diameter is not increased.

 

So, any idea on price and when it will be available?

 

WOW! that is some serious hp gains. NIce work UT!

 

Well, I understand what you guys are saying about the leaning out of the fuel mixture. I have to wonder if this would be the effect on every Z.

Also, we have not seen gains like this from any full exhaust on the market. Why would this item lean out the mixture and gain so much power, when even the true dual exhausts have not shown this big of a gain in power? Are the catback exhausts leaving something out, cause these results put the need of them in question and make you want to just keep the stock exhaust. Anyone test this with FI?

BTW, it does look a whole lot like the Fujitsubo Y-pipe, but they only advertise a 5 rwhp gain.

 

Diameter Sizing of the Y-Pipe is 2.375 and 2.875, thanks.

 

i think the big question(s) in the crowd are.....how much and when will you be selling it??

Ben

 

That thing looks too pretty to stick under the car.

I want it.

 

get two; use one as a hood ornament.

 

very similar, but not identical....

i have the full fujitsubo system (catback with Y,) just installed on my G....

notice the missing crossbalancer tube?? is it design, cost, or performance that caused it's moission on the UT version?? (or all the above?)



either way, the welds look awesome!! and the F&F appears to be top shelf!! (the fuji is about the same, but they dont have a polished Y pipe..

this reinforces my belief in the fuji i bought..... over TD systems for sure (on the vQ)

eS

 

This guys(esemes) gear box is practically glowing.

 

That's where an A/F regulator comes in handy.

 

Hmmm...regulator? Or monitor? If it's a regulator, what kind is it? I want to take a look at the website, get more info, etc.

 

I believe HKS, Apex'i, GReddy makes some.

 

Whatever little I know about exhaust systems is that the cats are the most restrictive part. Yet, people that replace the OEM cats with free flowing test pipes don't get nearly the gain of this Y-pipe. Am I missing something here???

 

No you're not missing anything. The y pipe will help, but it's not going to change A/F dramatically and certainly not enough to provide safe HP gains.

One should expect a 5-8 HPish gain at the wheels on a good entire cat back replacement. The y pipe alone will never produce those kinds of gains on this car.

Obviously these dyno charts should be taken with the same grain of salt that you would with any vendor posting dynos.

It looks great buy I'll bet my car against yours that this y pipe nets anything better than 5 HP at the wheels on a N/A Z or G, run on a dyno by a third party in controlled experimental conditions.

I'm calling Shenanigans.

 

Shenanigans................

.......Sounds like popycock to me.

 

i am down to get one if the price is not too ridiculous.


Thanks
