I've pretty much decided to go with the following setup:

JWT Pop Charger
Crawford Plenum
Crawford Headers
Crawford Cats
Nismo Cat-Back Exhaust

Anybody else have this same setup? I'd love to know how you like it.

 

If your looking for power gains you do realize that youd prob get better gains out of a simple lightweight flywheel clutch combo or add a 3.9 gear ration and blow all those mods away for the same price. Noty trying to flame though, i have the nismo exhaust and love it just wanted to say....

 

Gatti,

My main goal is to max gains and still keep my warranty intact. I have a 5 year, 75K mile warranty. Can I get those gains you mention and still be under warranty?

 

My next upgrade is the lightwieght flywheel and a clutch! I remember reading that the 8 pound flywheel made the car harder to drive!? Anyone know why exactly? I know most get the 14 pound one, since the stock is 23pounds right?

 

Id ask first but imo yes since a lightweight flywheel is just decreasing ratating mass on your transmission. Thats really a sticky one though. It wont CAUSE any problems but I know dealers always try and say that x mod caused y problem therefore we dont have to pay. If your worried about warranty get a jwt clutch flywheeel combo since that seems to be the safe mod. If they void your warranty they have to produce FACTS as to why said mod voided your warranty. Also headers, plenums, and cats will void your warranty also depending on who you talk to.

 

As much as I want to mod my Z I don't think I am. After talking to the service tech at my local dealership he's telling me that any performance goody I put on will void my warranty. However, I heard about this Mcpherson act and it claims that they have to prove (like gatti-man said) that the aftermarket part caused the problem. It all just worries me still. I have a 5yr service plan covering me to 100K miles. I thought about cancelling it and getting money back...but so far it has paid off tremendously.

It's a hard call...IMO

 

My car was sold to me from the dealership (used of course) with Intake and Exhaust, so it better be covered under my 6year 60k miles warrently!

 

Well you can always add light weight rims and exhaust. Those can NEVER void your warranty. Hmmmm a plenum wouldnt void your warranty either i dont think. Short throw shifter wont void your warranty. That should keep you busy for a while. Besides the light weight flywheel and short throw my favorite mods have been wider/lighter rims and exhaust since the stock potenza tires are crap anyways and the Z sounds sick with a new exhaust plus a little bit more power too.

 

Gut the secondary's on the stock cats, cheap free hp...

 

Now when you say reaplace the exhaust, do you mean w/ Nismo parts only? You don't think it would matter which exhaust I went w/ it still would most likely be covered under warranty? If yes, headers too? I was under the impression you could modify but ONLY w/ Nismo.

 

If you ran into a problem im sure they won't void your warranty due to them selling you the car w/ the performance on it, you would have the upper hand on winning that one. If it is Nismo stuff, it doesn't void it anyway.

 

How about APEX-i exhaust and alphawerkheaders

Any exhaust should never void your warranty. I mean its a cat back for crying out loud. Any dealer trying to void a warranty bc of an exhaust is full of crap. That being said the nismo is a good NA exhaust but their are plenty of others that are very nice also.

 

That sounds sweet! I havnt heard anything on the APEX-i exhaust, does it give good gains??? Another putfiler I see!

 

Surprised nobody mentioned the HKS TD Ti exhaust, gotta be the prettiest and it saves weight over stock just like Nismo. I think the power gains are similar to Stillen, with louder/deeper tone. The crawford headers get all the rave reviews, I think somebody earlier mentioned getting them and Jet-hot coating them... but I think they already come coated. For 1200 they should. JWT makes any exhaust sound better, I love the way my car sounds. Just the JWT pop-charger with Stillen test pipes, man it roars/rumbles like a small-block V-8 at WOT above 4k RPM's. I have heard Borla TD on 2 G35's, pretty good sound. The Nismo sounds good too, not as loud and less rumble than the Borla, but the Nismo was on an HKS supercharged car which also had stock cats and Nismo headers.

I think the HKS exhaust is gonna show the most power with extensive mods, the flow characteristics and volume capabilities are amazing.

 

What about w/ headers? Do you think that would void a warranty?

 

I think headers are considered a warranty void every time. Even with Nismo, they are R-tune not S-tune. My Nissan dealer said S-tune is warranty friendly while R-tune isn't, the R is for RACE where the S is for SPORT and they are labeled that way on purpose for warranty and street-legal type issues.

 

makes sense, thanks!

 

You want to make sure with your dealership about whether if you put headers on it will be covered by warranty or not because my dealership has covered EVERYTHING under warranty! So just check with your dealer if they would or not. And for the APEX-i it has been rated that it adds like 7-10whp or so....but I haven't dynoed the car since I have had it put on. As well, I put on the entire exhaust and intake at the same time so even if I did get it dynoed it wouldn't be accurate but for driving her, let me tell you from stock there is definitely a difference with the mods. Im taking her to the track pretty soon so we'll see what I run!

 

most exhaust give about the same HP, im worried about tq!
