I'm not sure if there's a 'best' exhaust for the application. You'd probably want one that has as close to 3" piping as possible. Otherwise, it's a matter of personal taste as far as sound goes.

I think my Fujitsubo Legalis-R sounds great with the kit. Perfect exhaust note for my liking (low rumble at idle, growl at wot). The single downpipe the kit provides made it a little louder (and better-sounding) than with my high flow cats.

You can also go with a true dual exhaust, but you will need to fab a reverse y-pipe to hook it up to the kit's downpipe.

 

There are several y pipe back exhausts that will work. Mine is the Apexi WSII exhaust. Piping is just under 3"

 

What about the model year? Does it matter that mine is 04.5 as far as the reflash goes? Also, you mentioned that you have the WS2. Does that include the y pipe? if not which one would you recommend.

This kit actually replaces the cats and y pipe so you dont need either. The WS2 is a y pipe back echaust and does not include one. For the flash the 04.5 should be set. The 05 is the only one currently not supported.

 

Damn thats sick, so there is a bit of cost savings from that standpoint. Do you know anyone that has already installed on 04.5?

 

Mine is a late model 04 in terms of ECU. So yeah I guess..me....

 

so how reliable is the turbonetics st kit... i really want one but my nightmare is having a blown motor...id run stock boost at all time.. whats more reliable

 

Turbonetics has a cat-version coming out.

 

I don't think a fuel system is needed until ~420rwhp.

And i'm going to take Charles' word for it that the CAS wire is not needed.

 

I'd suggest WI and/or NX ntercooler kit.

 

Anything y-pipe back would work. IMO, 2.75"+ would be optimum.

 

No blown motors yet and I don't think you will see any either as long as the owner is using the reflashed ECU that Turbonetics reflashed for them.

Frankly, most of these blown motors, as long as they are under ~9psi on any (turbo) kit, are due to the owner's error or mechanic/tuner error. You're chances of blowing your motor are actually very slim if you do some safety mods and don't go over ~9psi.

 

that mean i have to take out my ECU and send to Turbonetic to reflash? or they are included?

 

Yeah, you have to remove your ECU (Technosquare has instructions on their website) and send it to Turbonetics, shipping is included as is the reflash price. I believe it's a 3 day (at the most, really depends on what time it gets shipped and what day it is) turn around time. And i'm sure the installer will recommend sending it before they even get started on the install. (but the car is at the shop)

 

Charles said no CAS wire needed? My understanding was that the CAS issue was generic and COULD POSSIBLY effect any car (especially FI). I personally dont think its the big issue it was made to be earlier but it seems like its cheap enough to do (and rule out that issue).

 

I'm running a CAS wire just because I was able to grab one in the group buy. It is NOT needed, and there is really no hard documentation that it has been at fault for problems with other kits. I'm just running it for that added peace of mind. Once again, it is not required in any way.

But, if you want to grab one on the side and install it, then by all means do.

 

That's what I thought. However, if Charles makes the damn things, and tries to tell you that you don't need them before you buy one from him, i'm going to say that's a sign that they really aren't needed. (and it's not like it's some small/cheap part that he just doesn't really care if he sells or not, he sold quite a bit in the GB and is still selling them)

(I assumed it was ok with Charles that I told you this, he told me that the CAS wire is not needed in I.M., he told me he tells people they don't need it, don't buy it before they'll buy one from him, and that he is not running a CAS wire on his 575rwhp 350Z)


And, you may want to consider the source the CAS wire came from. If APS' 350Z was made before something like Feb. '03 and had the CAS TSB, then I could see how they observed scattered ignition timing. Maybe, they figured it was a problem on all 350Z's, and they had already set an MSRP on their kit and figured it was beneficial to what they were shooting for with the kit (no blown motors, a Feb. '03 350Z with no CAS wire with APS TT blowing a motor wasn't something they wanted to hear and I doubt they wanted to go through the trouble of checking other '03s, and after it was produced, '04s, and now '05s just for a ~$20 part).

(the above paragraph is all hypothetical, I cannot prove it, though it sounds like a reasonable thing to me)

 

The 03's that were recalled for CAS issues were for the sensor itself. I'm not sure if the dealer replaces the actual wire when it is repaired, but I doubt it.

The tuner that installed my kit says he has witnessed scattered timing on a greddy tt setup, but I'm not sure if it was from the wire or the emanage. He seemed to think that the CAS wire was a great idea, though.

 

Kinda off topic but I was speaking to someone that told me that greddy has an new emanage 2 coming out. He said the problem with the regular emanage is resolution is not that great.....what ever that means?

 

Probably the resolution on the maps you tune with. I believe GReddy is releasing a new E-Manage for the USA soon per a website I had seen, he had a picture of it from a magazine. Let me try to find that thing again, I was trying to find the name of parts (E-Manage accessories) I would need to give to Sharif when I get the GReddy kit.

taurran, didn't know that. Oh well, hypothetical situation anyway.
