Sorry if it's a repost...

+11PS (still about 11hp).

That's an interesting setup. Nice to see that there may be some options by the time I have a Z I hope it has a nice growl.

Default no...

i was wrong...they don't mention anything about stainless...it's going to be titanium and it'll probably cost as much if not more than the fujitsubo TI one...

Default Translation:

350Z R1 TITAN EXTRA

As for ‚_ normal horsepower no horsepower?

First from measurement of normal actual horsepower. This is the basic job which the ƒAƒ~ƒ…?[ƒY does by all means in computer setting and the occasion where muffler production is begun. As for the dynamo which is used in measurement the die/di no pack which has established reputation in accurate output comparison. As for result factor 1. With setting of 2 259 PS. When it is maximum value of the part in angle, 260. But 9 PS what as for disregard. Becoming the simply just a little air being collection of data as for the demonstration car of the option number and the other Z which have come 268 PS ‚Á ‚Ä stories being many. Being to be, the number with roller type chassis dynamo such as Bosch and ƒTƒNƒ‰ spirit vessel, directly it compares being not to be possible, but * & *. As for being thought in two one. The car inside it is good, but just a little it is little truly, or is the factor which is put on the die/di no pack little? 1. Factor of 2 1. It makes 24 with exactly being it becomes same, it does, but you do not understand true output difference it does not compare with the same dynamo at the same time.

Because you think, this time and, the option number comes collection of data next, Bosch 268 PS is in the die/di no pack some horsepower the meter ‚Á ‚¿ ‚á.


So, maximum value of power rise is verified.
The Z of this time is the NA. Like the turbo in boost rise therefore the reason which it cannot depend, the role which is carried out in that power rise is serious! Especially, when with exchange after the catalyst, still safety standards conformity is considered, it includes ascertaining the back to back balance, volume and power, not doing the data taking which is made the ƒLƒbƒ`ƒŠ it cannot go, * & *. So, as for the ƒAƒ~ƒ…?[ƒY when you say first it did what, * & *, the straight tube which ignored volume! So is, the muffler of the simply pipe, with the NA how thinking that, number of pies without entering, it produces the muffler of the large aperture which probably will be. The extremity of the peak power which muffler exchange makes possible is ascertained. The result records the power rise of normal ratio 13 PS, substantial this it is the case that it reaches maximum value of the power rise which becomes possible at the time of exchanging after the catalyst. Sound arresting the silencer whose it is possible to do, - it makes the maximum value which the straight tube makes possible in regard to the volume which becomes problem next, as much as possible without shaving. In regard to this, because the full titanium muffler which corresponds to the advanced NA engine of the new generation many there are the details which it tests and it develops, structure, layout and main pipe diameter, the silencer - it enters on the basis of that data and the aperture and the silencer - inside diameter and the silencer - decides capacity. The result in the loss of only 2 PS, achieved the approach exhaust noise 89 db which clears preservation reference level with room from 13 PS rises which the straight tube makes possible and the ‚¿ ‚á was. As for this muffler exchange after the catalyst, not to mention the muffler of safety standards conformity, being the case that it means the fact that the power rise of 11 PS is made possible by the NA vehicle, normal muffler weight 22. 3 kg only 8. In 7 kg! How, it adjusts to the merit of light weight conversion only of the full titanium muffler which is said, pulls up the maneuverability largely. And furthermore delightful thing is another. As for that the sound quality is the ƒ?ƒ`ƒƒƒ?ƒ`ƒƒ to be good the finish the ‚Á ‚¿ ‚á ‚Á thing. It meaning that combination of the unique layout like the part and the photograph which are the full titanium muffler in regard to this is large, it does, but from first it is to be good so much, the ‚Á ‚¿ ‚á ‚Á ‚Ä is good kana? The ‚Á ‚Ä the extent which is thought the ‚Á ‚¿ ‚á it was in good sound. Speaking concretely, volume itself it is quiet, but when it turns to high revolution, the calling, ƒNƒDƒI?[ƒ“ entering, hurting, it does. Having tried this ‚Á ‚Ä to insert, very, when there are no any which are inserted and they depress the accelerator largely the ‚Á ‚Ä, without either confined sound of the medium speed low, the ƒNƒDƒI?[ƒ“ you call, the new timbre exhaust noise of ideal, in the domestic sport car you have not heard until now for the sport car was possible and the ‚¿ ‚á was.



Weight R1 TITAN EXTRA 8. 7 kg normal 22. 3 kg



--------------------------------------------------------------------------------

R1 TITAN EXTRA Dynopack Data
This power graph of the latest test. Red normal, green of course the R1.

In case of the muffler of the NA car, in order those which are less than normal in comparison with the one for turbo car is many, (to clear the volume for safety standards, the silencer - squeezing inside diameter largely causes, low-speed torque concern, would like to see sells in expression only such commodity, but it is the far distant rear silencer - squeezing from the ƒGƒLƒ}ƒj, low-speed torque something it rises absolutely and increases is) the pipe diameter, the silencer -, many know-how such as inside diameter and capacity is necessary. Especially in case of the latest Z, as for power rising, haphazarily, you did not want to make the muffler whose volume is large. Because (everyday you ride by your, also the neighboring way thing) with nighttime thinking that you adopt, the latest layout. Like the photograph being thin, the long silencer -, the sound-absorbing area vis-a-vis the inside diameter the fact that it can come off largely feature, furthermore that silencer - by the fact that you use with the twin, not to be the sound arresting which squeezes inside diameter, is the case that sound arresting with the method of increasing the sound-absorbing area becomes possible. In spite even in the quiet exhaust noise, result and the approach exhaust noise 89 db it succeeds in the power rise of 11 PS at the time of 6097 rpm, as in the graph has succeeded in 15 PS thing power rises in the time of 6600 rpm of top end altogether in sacrifice, low-speed torque!

As noted by Underpressure... low-end torque gets cut... Not good, in my opinion, and the problem with some aftermarket systems.

Victor... is your new exhaust system for real ? or are you just playing with your PS skills.. ??? nice blue a## pix of your baby ! if true.. what did you install ?

Gendo Ikari -- nice catch.. yes, this was part of the Option pictures posted about a week ago...

NOTE: This exhaust system is titanium... and cost JYen 198,000...or about US$ 1,623 (US$ 1.00 = JYen 122)

VQracer-- What kind of exhaust is that and what kind of performance are you getting from it?

Gotta wonder how loud the exhaust must be with the straight pipe option? +~26HP is quite tempting...

Daytona...do you have any idea how loud a straight pipe would be?!?!? My GF's dad has straight pipes on his 911 race car...when he starts it in the garage the whole house shakes! Still...26hp...heh

Am I looking at the dyno graph wrong? It looks to me like torque is higher almost all the way through the rev range with the exhaust, and the losses are very minimal down low.

J Ritt, I see what you are saying. Looks the same to me. Only thing is that the torque dyno graph is displayed in Newton meters and if the graph were to be converted to a more precise measurement (ft/lbs) the small losses might be able to be seen better. Just a thought though. I could be wrong.

There's 2 different dyno charts. One appears to be of the catback and the other of the full system. There's a page for the full system. You guys got that covered in this discussion? seems like there's ambiguity here with which exhaust, full or not....
Loss of torque seem so to only be with the full system, not the catback. The torque loss with the full system is minimal for the amount of torque and HP you gain where it counts.

well... this appears to be the chart for the Full System. Small amount of torque/hp loss <3k rpms, but look at how much torque and HP you gain where it counts.
