Okay, so we all know there are a couple of them out there. I know a couple off hand, but I'd like some opinions before making the final decision. Basing it off of performance, sound, and cosmetic looks - which true dual exhaust do you guys think is the best for the 350Z? Stillen claims that its true dual setup produces the most respectable gains out of all the others. Is that true? I have the Stillen TD right now, but I don't like the way it looks or sounds. You can't tell it's not a factory exhaust by looking at it, which leads me to like the one made by Altered Atmosphere Motorsports, with its dual pipe look. Opinions, please.

 

Hks Td

 

i would say aps IMO

 

I'll have my Borla TD installed Thurs. You're more than welcome to come to my shop and take a look at it. The shop is in Glen Cove.

 

I prefer a dual exhaust with two mufflers rather than one muffler with all the 90 degree bends. Just a personal preference.

 

Borla...nuff said

 

the stillen true dual is actually heavier than the stock exhaust system, so the extra power you suposedly gain from it, will most likely be negated due to the added weight. the Injen SES True Dual is the lightest dual exhuast system that i know of, that is why i put it on my Z. next exhaust system will be a custom x pipe set up with some borla mufflers.

 

To the post above, a 10lb gain from an exhaust will not negate the extra power from the stillen true dual.

How about the greddy evott?

 

I'm hopin to get my hands on a fast intentions intimidator soon. Heard nuthin but good things about this one, although I haven't had the chance to hear it in real life.

 

if u r goin to go f1....either aps td 3inch or aam td 3 inch....staying naturally aspirated....hks td or maybe even evo tt since its 2.5inch also...

 

hks td

^ Fast Intentions exhaust on a G. Sound pretty nice... I like how it's throaty instead of high-pitched like a four cylinder.

 

i've read the borla is just a few pounds lighter than the nismo. So injen is the lightest??

 

People have had trouble with injen - the packing in the muffler apparently spews everywhere. Not sure if they fixed this. Here is what I think the diameters are for these exhausts (not 100% sure on the injen and HKS):

Injen 2.25"
HKS 2.36"
Stillen 2.5"
FastIntentions 2.5"
APS 2.5"
EvoTT 2.75"
AAM 3"
APS 3"
SVRT 3"

I was gonna say pick an exhaust dependent on what your going for. The APS is nice but 3" is more for a Turbo app. HKS and the Evo seem to be people's top pick with the APS not far inline.

 

BTW what is the stock exhaust size?

 

Injen 2.25"
HKS 2.36"
X02 2.5"
Stillen 2.5"
FastIntentions Intimidator 2.5"
Fast Intentions Dominator 3.0"
APS 2.5"
EvoTT 2.75"
AAM 3"
APS 3"
SVRT 3"

added some

 

stillen is 60mm, or 2.36 inch

 

The problem is that I'm really not sure which route I'll end up taking - supercharged, turbocharged, or built N/A motor. I change my mind every week. Either way, none of them are something that I can do for the time being due to a case of insufficient funds. But, I'd like to get a little more performance out of the Z, as well as make it sound different from all of the stockers. It's such a tough decision to make... I bought the Stillen on impulse because I'm a Stillen dealer, and they told me that it was the best I could use. But, I just don't like the way it sounds! I gotta spend more time youtubing exhausts.
