Exhaust weight question
I've been searching, and lots of info helped me out on which exhaust to
get and stuff. And that it doesn't add much hp even with new exhaust system which costs quite a bit of money. Anyways, to get to my question;
I'm thinking to go for a all Ti exhaust system.
I'm lookin at fujitsubo,stillen and hks.
I don't want go for hks since the sound clip doesn't really make me to cling on it.
My choices are pretty much shrunk to Stillen and Fujitsubo.
My understanding is that, I'm looking at about 10~15whp gain with the aftermarket exhaust system right?
So, I was wondering how much weight advantage i will have over SS systems.
I DID the search on it, found out that someone here at a workshop runs a
stillen Ti exhaust that is 60lb lighter than the stock system. Which i think
is tremendous amount of weight reduction, considering you don't save as
much over with aftermarket wheels that much(i know i know rotational mass = approx.
2 X mass from other parts in the car) If i were to get a 15whp boost with
60lb weight reduction. Wouldn't that mean "Quite a lot faster than stock"?
If so I'll spend extra dollars on getting Ti exhaust system.
Lastly, For those of you who has ALL Ti Fujitsubo exhaust system.
Do you know how much weight reduction you've got after the replacement
The same question for the HKS as well.

I don't think Stillen, HKS, or Fujitsubo even makes a full TI exhaust to begin with. I know that HKS has Titanium Tips which is pure bling and not much weight savings for an exhaust that costs $1400-1800.
In regards to weight savings, a full TI exhaust will definitely do that for you, but as far as whp gains it will depend on your setup and it will vary from one exhaust to another. Just search on each exhause that you are interested in and threads will pop up.
As far as performance gains in the speed department, unless you are a good driver you won't notice it much but every little but counts. Just keep in mind that traction with the Z is already an issue and if you lighten up the rear end of the car and the lower section of the car as well it will have more traction problems, so you will need to corner balance your car with a full coilover system to see the true benefits of weight reduction.

hks makes a full titanium exhaust but its not the true dual model....
IMO you will probably make about 8-11 whp..not 15whp
with lets say a JIC titanium exhaust liek i have.... 9lbs yoou save about 50 lbs on weight....
in any caseyou wont feel it much on the read unless you really track it...
you also gotta consider the sound level on the exhaust... you looking for a loud system, quiet system... what are your future plans... you planing to stay N/A or go FI?

Weight savings on exhaust alone won't do much. If you want to feel the difference, get some very lightweight wheels FIRST THING, and do some other weight saving stuff.
There are several threads on weight savings already, if you look around you'll be able to find them.

First of all,
Thanks for the inputs guys.
I'll share my plans with you.
I won't go for F/I unless the new 07 gets approved of blow-less
As I'm a student I won't have much money or time to build a built motor.
I don't think we have that many SKILLED mechanic around Vancouver to be
trusted(I could be wrong). My plan now, is stay N/A.
Wheels - I'm trying to get 18" for the aftermarket wheels
[Volk GT-C, TE37, GT-S(this is too heavy so prob not)..etc.]
Intake - Anything that gives me a gain (not a pop charger tho, i heard
about putting the gear in neutral is gon be scary)
Exhaust - I prefer quiet deep sound, like injen,nismo, stock sound
instead of loud fart noises. I still don't know much about header to cat area
so, still learning LOL.
Suspension - Thank you Rick, gave me gread advice on weight-distribution.
I was looking into tein adjustable coilovers(which costs a lot).
Other - Some bodykits to dress up,sway bars.ight weight battery..spacers
etc..
basically, I wanna give "woo A souped-up Z" impressions, but i don't want my
Z to lean only towards the looks(that's why i plan on going 18" wheels
instead of 19" to save every bit possible) I really want to learn DRIVING
with this car. I'm not planning on selling it for a long time either.
With my antcipation on weight-reduction, I plan on saving weight of a girl
passenger(around 110~120lb) with some 20~25 whps gains.
But now I think about it more..putting bodykits(dont' know how much they will
weight),some sway bars, plenum spacer will increase the weight i decreased
from other models. Slapping a turbonator sounds hella fun tho..
maybe I should gather all my money from doing all the NA mod to do make a
built motor..(how much will this roughly cost? I will search but outline of
price will help me determining my budget)
What do ya think?

ok, let me shed some light here
1. stillen does not make a full ti exhaust
2. Fujitsubo does have a full ti exhaust - I have it on my car
http://www.z1auto.com/prodmore.asp?m...ust&prodid=307
I forget the exact weight as I installed it a long time ago but its in the 25 lbs range.
3. HKS Kansai offers a full titanium exhaust for the Z:
http://www.z1auto.com/prodmore.asp?m...st&prodid=1717
it weighs in at 19.6 lbs - insane!!!
4. the HKS exhaust you have found clips on is not titanium - only the tips are titanium
Given the sound you want the Fujitsubo would be a perfect choice. I've yet to hear the Kansai but I'd love to

NOT a bad choise to stay n/A

[Volk GT-C, TE37, GT-S(this is too heavy so prob not)..etc.] if you want a show and go deal go with 19s..they fit perfect IMO look to spend around 3k here on wheels and tires.
Intake - Anything that gives me a gain (not a pop charger tho, i heard
about putting the gear in neutral is gon be scary)
Injen cai is a good choice, if you get a lot of raing down there you can quickly make it a short ram
Exhaust- I prefer quiet deep sound, like injen,nismo, stock sound
instead of loud fart noises. I still don't know much about header to cat area
so, still learning LOL.
definatly get resonated testpipes(with non fouler mod) or high flow cats. INjen is not a quit exhaust, but the Ti tip injen is just hella hot and owrks great NA. IF you look for quiet and true dual for better nA gains, then go borla.

definatly get the plenum spacer 5/16" + mrev2. do not get the ssv or pulleys

With my antcipation on weight-reduction, I plan on saving weight of a girl
passenger(around 110~120lb) with some 20~25 whps gains.
the Z is heavy anyways(is not a 1000 lb crx, where if you ate a macdonals you already screwed you 1/4 time) so not a whole lot you may gain with weight savings if you plan on doing some street racing every once in a while. You might wanna consider audio too so that addds up more weight... Some simple weight reduction thing is when you get your 19s and tires remove the spare tire and jack

built motor..(how much will this roughly cost? I will search but outline of
price will help me determining my budget)
from the sounds going turbo and build engine its way way out of your price range... if you can save 6k you can do a supercharger insallted and maybe even tuned. easy.. consider then adding another 1.5k in clutch flywheel and about 500 in decent gauges.....
so it adds up, but if you mod your car n/a and later do the 6k for supercharged, most fo your mods will be ok by then. At worst you will loose your Injen cai, but that is only about 150$ which you can sell it back...
Supercharger is also the safest of all FI options.
Once you are done doing a lot of mods to your Z n/A get an ecu..utec IMO and then you will max out yoru n/A mods...
If you plan on adding sway bars, then just do tein basics
Remember with coilovers, your ride willb e lower, which means alignament... which also means, you might need camber adjustment too
modding is fun.. but its never ending D

The car dying in neutral is discussed in one of the posts there.
There is nothing wrong with the popcharger. Simply don't put your car in neutral at high speeds.

If you REALLY want to lose weight Single Ti is the way to go. and also some test pipes. Or go all out with the Amuse Ti Ypipe+test pipe. Thats going to be "LOUD!". I just installed test pipes in my Z with the single Apex'i Ti exhaust. You will feel a really nice difference if you could stand the loud exhaust.
