I wouldn't say that. The Stillen exhaust is one of the best as far as power gain is concerned. It also has a very nice sound, and competitive weight.

It might be wise to wait for the Berk exhaust to see what they come up with, and even Borla's might be worth the wait.

Competitive weight? It is the heaviest exhaust I have seen for the 370Z so far. AAM is lighter by at least 5 lbs., and the Fujimura is 10 lbs. lighter than stock which is way lighter than the Stillen which is around 10 lbs. heavier than stock.

Granted we need weights on more exhausts to see what is the norm, but from what I have seen so far the Stillen is heavy as hell.

But in a competitive sense, how much gain is in the AAM or Fujimura (I have not seen dyno results from those two)? The Stillen offers one of the highest rear wheel HP gains from a CBE so far and only adds 10 pounds. Now if AAM or Fujimura can get close (does not have to equal) in performance and reduce weight then it is a tough call on which is better then.

That is all personal preference. I am just pointing out that this guy said the Stillen has a competitive weight, and from what I have seen, that is a false statement.

miguez · 06-23-2009, 09:55 AM

Being a false statement or not depends on what you are considering, as theDreamer mentioned. Most exhausts that add significant performance are heavier than the stock exhaust, basically due to the stainless steel used in their manufacturing, and partly to their design. So, given Stillen's choice of material, acquisition cost, and mainly their performance gain and sound note, that is competitive.

If weight is a major priority, full-titanium exhausts are available, some with good sound quality, but their price is on a different scale.

import111 · 06-23-2009, 10:00 AM

Find me an exhaust that weighs more than the Stillen and I will not call your statement false. You said the Stillen exhaust has "a competitive weight". As far as I can see it is the heaviest exhaust for the 370Z out right now.

I just don't like miss-information spread around the internet. My research shows your statement about the Stillen exhausts weight to be miss-information.

semtex · 06-23-2009, 10:14 AM

Guys, it's not just about weight. Power-to-weight ratio has to enter into the equation as well.

Caravanshaka · 06-23-2009, 10:18 AM

and, the weight is more in the back, which isn't necessarily a bad thing. Now, if you were adding more weight up front that would be a different story.

miguez · 06-23-2009, 10:31 AM

import111, I am not comparing it to other after-market exhausts, but simply to the stock. To me, adding 10 or 11 lbs over the stock for 18 whp gain makes this a competitive advantage over the stock. Again, each person's interpretation depends on what is important to them.

M.Bonanni · 06-23-2009, 10:35 AM

Also remember that the exhaust system is low and centered, which is pretty much the best place to add weight if you have to. Weight gain/loss will hardly be felt here if at all.

Back to the Berk exhaust please.

I really think you are thinking about this incorrectly. What MigueZ said was not mis-information NOR was he saying that its the lightest exhaust out there.
What he is saying is that the Stillen exhaust isn't light, but it isn't terribly heavy. Yes, it is heavier than stock, but it isn't heavy to the point where its weight can offset its gains. Therefore, I will agree with MigueZ that the Stillen exhaust is still competitive weight wise.

Oh hai Berk

M.Bonanni · 06-25-2009, 04:24 PM

Ok so Berk is going to try and have my exhaust ready for me to pick up on Sunday while I am down in their area! If I am able to get it, it I will shoot for a baseline dyno on Monday and install Monday night. Put a few miles on the car and shoot some videos Tuesday, re-dyno Wednesday.

N!!!!

bostic220 · 06-28-2009, 07:31 PM

Were you able to pick it up today?
