I am deciding which exhaust to get... the Injen SES, Borla True Dual, Stillen True Dual, or Greddy True Dual. I know the Greddy isn't available yet. Advantages of Injen SES, gives nice solid hp gains, sounds very nice, goes good with the intake, uses flanges, and angled tips (like on FI Supra's etc.). Disadvantage's of Injen SES, sounds ricey to some people, stainless steel so it's not the lightest, the tips are a little weird and big imo. Advantage's of Borla True Dual, okay hp gains, good warranty, and it sounds awesome also. Disadvantage's of Borla TD, clamps instead of flanges and looks cheap (then again who is going to see them?), doesn't utilize the "true dual" setup as Injen does, not as good of gains as thought. Advantage's of Stillen True Dual, looks nice, decent gains, sounds good. Disadvantage's of Stillen's TD, sort of doesn't utilize "true dual" setup, heard a couple of bad rumors, don't know what kind of connector's they use, sounds 'choppy' in one video of it. I don't know any advantages or disadvantage's of the Greddy TD because it is not out yet... What is everyone's opinion on what exhaust is best out of the one's I have given everyone to pick from? I just can't decide...
Added the Amuse R1 also...

 

I am also in the process of deciding which exhaust to get...So far, the Injen SES setup seems to be the best looking, loudest, and best gains in hp. I mean really.... if you look at one of the pics of the Injen setup on a lift it is obvious that this is the real deal (True Dual and the best angles to free up the most airflow possible). The borla to me just looks pretty much like the stock setup with some Borla badges. In my opinion, the looks of the Injen is awesome. I want an exhaust that will let people know that I mean buisness.... Also, I want a setup that is loud as f*ck. My last car was a 2001 V6 Firebird and I put on the borla true dual setup, but it was never that loud at all. I know the Z has a lot more power to to make some noise with the Borla system, but after hearing all the clips, the Injen sounds by far the best and loudest. As far as price goes, I couldn't care less if the Borla costs 200 less than the INjen. I didn't spend 36,414 on my Z to go cheap when it comes to an exhaust. If the Z came with the option for an exhasut similar tot eh Injen exhasut from the factory for even another 1,500 I wouldn't have thought twice about getting it. Ok, im done....

 

Injen- nice gains, but 2 angled mufflers don't look good (imo)

Borla- sounds nice, price is cheap, but they didn't live up to their claims (some people lose hp somehow a little after the install)

Stillen- have no clue, but I only heard bad stuff about stillen

Amuse R1- don't know much about this one, but I think it's
titanium, REAL expensive, but you'd be willing to pay every cent if you heard it, there was a soundclip somewhere on the forum....

 

Ditto,
I just installed my Injen last night and it does not sound ricey at all. It is a very deep tone. For those of you that have heard or have disconnected their stk muffler temporarily for kicks, it sounds that low.

When I start it up it has a nice rumble w/ a nice low tone, but a minute or 2 later it's almost as quiet as the stk exhaust at idle.

As for the weight, I didn't weigh mine, but most have posted lighter weights than the Borla, which is good considering the Injen is also SS.

All and all I'm very happy. I understand that the look of the Injen is not for everyone and I respect that. We're all different.

I had a turbo DSM prior to my Z and had grown to really like the angled look of my exhaust and other angled exhaust on the market for turbo cars such as the Supra, Silvia, Skyline, etc.

That's why I chose the Injen: my style exhaust, much louder than stk, polished SS, and I got it at a great price.

You can't go wrong with either exhaust, Borla or Injen. I think I've said this several times already.

Although it's nice to be different sometimes, I can't see my self paying $1000+ for the other JDM exhausts. But hey if you can dish out the cash go for it, but make sure you gain some decent power (10-15whp).

Good luck.

...and no I won't be dynoing anytime soon, besides I don't have a baseline dyno. The Z definitely felt quicker during my first run after the install. Revs quicker.

 

A little off topic, but how much did u guys pay for the Injen SES and from where? Thanks.

 

Got mine from www.ConceptZperformance.com
Ask for Coz.
If you don't have an intake yet you can get a deal on the CAI/exhaust combo.

 

OK I have had about enough of this "which exhaust should I choose?" .The answer is none of them!!!!

Don't care about looks, don't care about sounds, I want performance, all out pefomacne.

Yes you gain your 10 maybe 15 rwhp in your high RPM's/peak, but then when you go for your midrange you have lost, which is what people are complaining about as far as loosing horsepower. Some of you just look to make more horsepower in general instead of looking at what really matters, overall powerband.

So I am not willing to pay $1000 for some exhaust let alone even $700 for the borla just to watch my midrange power disappear

If it was up to me, wait and see what the market is going to bring to the tables, before you start jumping on the band-wagon of which exhaust you might get.

Please stop spreading this false rumor. If you're referring to TXSTYLE's temporarily-posted dyno, he NEVER LOST HORSEPOWER. His confusing use of the word "less" meant less than previous gains (which are still gains).

So, 7hp less than best dyno, 2hp less than best dyno, etc... all mean THAT THERE ARE GOOD GAINS, just a difference between runs.

 

What are you taking about? I saw gains across the entire powerband in hp and torque. Let me know and I'll repost my dyno's.

If you're waiting for that 35hp exhaust you've been dreaming about you're going to be waiting a while.

Don't like threads about people comparing exhausts? Feel free to not read them.

 

Ya', that was an impressive first post by him, eh, what's his name!

 

Exactly.

 

Number show nothing,when I get into a car I want to feel the difference. Now don't get me wrong it shows that there was a gain but it not to the entire band.

I can tell you right now I have been in a 350z with the borla and from a 3rd gear punch at about 3000 rpm it was signifacntly slower than my stock 350.

Now to me there is something wrong with that, I should be gaining power every which way not just at the peak.

For you guys to tell me that I don't know what I am talking about is pretty childish just because it was my first post on this board.

Let me ask you this, have you been in a Z with the borla exhaust? Well if you haven't then you wouldn't understand where I am coming from.

I am glad to see that you guys learned to read because that can be very useful in life.

But numbers aren't everything. For a car to be fast it need to have power every where or at least in my eyes. From what I have witnessed is that a stock Z with be faster in the midrange than a Z with the borla on it.

-David

 

You must be outta your mind. I can "punch it" at any RPM in any gear, and it feels 10x faster than the stock exhaust. I'll even prove it when I go to the dragstrip.

 

Wish you where closer, I would love a ride in a car with exhaust that makes it slower.

-David

 

Whatever you say, fruity.

Go get whatever exhaust you're going to get, and then come race me at the strip or the street. Then you can talk.

 

Have you been in a 350Z with a Injen, or actually any other exhaust besides the Borla? Failsaf3 said he gained hp across the entire powerband, he owns a Injen SES exhaust system, he should know... Your butt dyno doesn't approve of Borla? Most everyone who makes exhaust has already came out with their's, so your waiting for nothing. Also, about this: "For you guys to tell me that I don't know what I am talking about is pretty childish just because it was my first post on this board." What is childish is acting like you deserve respect for the first post, especially since you probably have not had enough time to browse around and see what exhausts are gaining what.

 

Ok now it has come to name calling WoW, I thought you where immature, but now I have really found out that you are just what I said earlier "childish".

I just told you what I have witnessed and that is how I feel not telling any one not to buy. Just that why waste all that money for nothing.

Save it for a better perfomance exhaust or part.

just my .02

I am not going to fight with you any more. Just a bunch of wasted space. Good luck with your exhaust and the best to you...

-David

 

Quote me where I called you a name??? I re-read my post and no where did I call you a name, or insult you.

 

Pretty sure he was referring to the fruity comment made by someone else, not you.

 

I thought he was referring to me, my bad.
