I would like to find out which unit gives you a more agressive sound?
A APS Tall Boy Plenum with of course the Mrev 2 or
A Crowford Plenum with the same lower plenum or
A 5/16 spacer with the lower plenum ??

all have the same gains pretty much, mabe a few off hear and there. I also am gonna go FI soon as well so keep this in mind on your opinions. Also i no people are Fi with the Spacer but that just makes me nervous of a leek, but havent heard any problems of that yet though.

all input is appretiated thanks

I also heard that crowford doesnt make the upper plenum anymore? Is that true? Crap!!!!!

 

The sound for all of your options will be about the same, and it won't change much from stock.

Adding a popcharger will make your car much louder at wide open throttle.

So will changing the cats for test pipes.

So will adding a catback exhaust system.


If you go F/I a leak from your plenum will not be a concern even with a spacer if it's installed properly. That being said, you can always cross that bridge when you come to it. No need to worry yourself before you have the turbo or SC kit in your hands.

 

Haven't the faintest what you mean by aggressive. Two members have the same setup. One says aggressive. The other rice.

Go forced induction, and forget these trivial bolt-ons.

 

Agreed- says two guys with trivial bolt-ons....

 

+1
internal mods won't do much with more agressive sound IMO.

 

Everyone Keeps saying that the PopCharger makes the car louder at WOT. I just installed mine last night, took about 30 Minutes. Went and took her out for a spin to test, and I hear a slight whistle when I punch it, but not that Deep sound everyone raves about, maybe its to new? Maybe it needs to be broken in?

 

or maybe its an over-rated filter strapped onto the stock piping?

I think the aftermarket plenums are gonig to be produce more sound then just a spacer. More wide open room underneath the plenum therefore causing more air movement sounds. HP wise, i would go for the spacer only.

 

So in that case thanks for the useless information my350z.com I just spent 120 on something for a nice sound that doesnt do jack. Half the times I'm not sure when people are serious on here.

Any other Forums out there that take things serious?

 

So I guess my idea to replace the stock horn with the sound of a roaring lion isn't what you would be looking for?

 

Maybe my hearing isn't what it should be, but I didn't notice much change in sound when I just finished my MREV2 with 5/16 spacer install a few days ago.

 

I apologize if this is a stupid question (because after searching for about 20 hours I can't find even one person who has asked it before), but everyone always talks about the great sound from the JWT Pop charger. Doesn't the Stillen sound just as good, or is this a JWT-specific phenomena?

 

After having the charger for a week now. I have to give you guys an update. The sound is noticable and I can hear the "Whistle" Sound. Its actually a nice sound when you open her up. I'm pleased with this buy.

 

350ztech is serious just not as many members i come here for a laugh when people get flamed

 

If you just want "agressive sound", trade in your Z and buy any crappy mustang gt, and throw a flowmaster on it. Maybe even sign up for their forum. I heard those guys were serious... no joking ever. Mustangs are like buttholes, right?

 

To be honest as I used to have the SSV installed on my car, that was the most aggressive sound, I could no longer hear the pop charger. Only what I can describe as a deep metallic growl in high rpms that sounds like it is amplified in a long empty hallway.

 

Yeah, my neighbor commented on his Mustang GT's sound compared to my Z.....I replied I get 27 MPG highway with 300 HP and 0 to 60 in 5.5 sec, I won't hear his exhaust behind me.

 

Too true. The threads with the most responses here are usually about how loud the car sounds and how big of rims you can get on. I can't figure out why so many Z owners want a car that looks and sounds like someone wearing a half open silk shirt and gold chains is going to get out of it?

Then they want you to pay for a premium membership. All they NEED to do is get all the people using this site as free advertisement by posting and sending pm's (geez!) to pay for ads. Most sites deplore this behaviour.

There is some good info here. You just need to spend hours searching...

 

..then A 3`` single is Joe Pesci in ``Goodfellas``. Aggressive. Well, close. A 5/16`` spacer does zip, nada, nothing for sound.

 

just save the money and go f/l. if youve done the research your wasting your time trying to get 5 or 10hp out of every little expensive mod. dont blame my350z.com that your to lazy to actually read and study about your own car. intake and exhaust make your car sound good thats it. until you go f/i save threads like this for more important questions.

 

I don't want to be argumentative, but he probably asked this question AFTER searching/reading many threads where members have made absolute claims that their newly installed spacer, lower collector or plenum made the engine "growl" more and sound much better.

Not everyone wants to go F/I. There is too large of a variety of reasons for me to even attempt to list, but many Zed owners would not have F/I if you gave it to them and installed it for free. It is a personal preference.

Many of those same people do want to squeeze every available hp out of their N/A engines by increasing efficiency. These same people may, understandably so, also wish to add mods that enhance the already beautiful sound of the the VQ35. They do not care if it costs twice the money. For some of us, it is not an issue of money, but rather an issue of priorities and goals.

Not everyone mods for the same reasons or with the same goals, because not all of us are looking for the same thing out of our Z's.

I read (almost every day) where someone comments that their new spacer or plenum mod gives them a "much" better or more agressive sound. Some have claimed it even changed their exhaust note.

Like I said at the beginning, I do not wish to sound argumentative. I am only defending the OP's premise that led to this question. I am happy to see this question evoked yet another good response from Wired, which will go into my mental notebook of various scribblings, where it may be accessed again from time to time.

Thanks again, Mike.
