I don't like the sounds of Stillen exhaust at all and I'll rather wait for Injen or something else down the road.

 

That doesnt sound all that different from stock.

 

That sound clip is only low revs and in a garage so doesn't seem like a worthwhile upgrade from stock, but I'll reserve judgement when I hear WOT as that was the best feature of a Stillen exhaust for the G35.

Here are sample clips of various exhausts for G35/Z including Stillen:

Many of those sound clips were recorded with better sound equipment and the test car may already have other mods so not an apples to apples comparison.

 

I think both APS and Fujitsubo sounds the best.

 

i remember hearing a clip of fujitsubo on an g35 i think i liked it the most, but it didnt give the most power. I believe it was borla but im not sure it was a while back..

For he g37 whats the exhaust that gives the most power as of now?

 

I was skeptical at first but actually hearing the exhaust in daily driving it sounds very nice. I'm hoping that adding high flow cats doesn't change the sound any. The only complaint I have is the tips are cut straight rather then angled.

 

i wonder if there going to be any more productive exhaust that can beat 8hp.
???

 

I was at Riverside Infiniti Friday and they had just finished installing 2 of them...

Looks pretty nice...

 

installing what?

 

2 Stillen Cat Back G37 Exhausts...

 

I have this on my Z. Great exhaust, but not much louder than stock, I remember it having a decent rumble over stock at 3500 rpm's and higher... I'd do a sound clip for you guys, but along with the Stillen dual cat back exhaust, I have test pipes and Top Speed Headers... Not to mention an intake and upper intake plenum, so you can't get any idea of the sound...

Too loud actually, I need a stock G37.

Edit: One thing I do remember about the Stillen exhaust: the tips were uneven at the end, hopefully something they have rectified since then, but one tip would be sticking further out past the bumper than the other... I know that has to be a deal breaker for some, especially when it's on an Infinity.
