I appreciate your Input very much.
Really appreciate the info and the videao/sound clips!!
Did you do any testing to determine gains over stock, or were you able to tell any performance difference?
HP from an exhaut is just an added plus. You should buy your exhaust based on looks, sound, quality, and price. All exhausts are going to perform about the same in a n/a environment, so no reason to even throw gains into the equation.It is interesting that the SportZ magazine tests showed a max gain of 8 HP for the best and a loss of HP and torque on the worst.
Stillen still claims 16HP gain, but I do not see any other manufacturers publishing any numbers, which tends to make me think that any gains may be incidental.
I appreciate the input, since you have used the Evo 2 exhaust.
hi all. Just have a few questions on the Greddy Evo2 exhaust?
-Is it true dual?
-does anybody have pics of the exhaust installed on a Z?
Are you running test pipes with it?Completed install of Greddy Evo2 on my 2003 Track yesterday, with the excellent technical assistance of Zivman's PM's
I like the "tone" of the exhaust very much, however I didn't realize how loud it would be, and the sound clips definitely do not give you the "true" picture.
Sound is very deep and definitely not raspy or unpleasant.
Did not do Dyno before or after based on forum statements which indicate insignificant gains.
I am very happy with the fit and quality of the system.
The greddy is one of the quitest exhaust out there, especially on stock cats.No test pipes- stock Cats.
Just used to very quiet stock exhaust.
Do hear inside car more than stock , but not objectionable.
