No in-car yet, but revving is available already.

YouTube - Berk Technology 370z Dual Exhaust Prototype#1

But this is without the X pipe, isn't it? Just asking, as I am compiling my "mods" list until my 370Z finally arrives...

Correct. This was the first 'raw' prototype, which was true-dual if I remember correctly.

Need MOAAAAAR......

Were working on getting the final prototype finished and more video's should be up soon

:tup:

I hope berk is ready for the group buy cause I know I am haha.

omg can't wait till the final product is done!!

Don't forget to get a weight on this exhaust. Weight is going to be my 1 of my big deciding factors.

Most stainless aftermarket exhaust are slightly heavier than stock but I would not allow that to be a deal breaker. For what you make up in power the extra weight is negligible.

Ok so this is probably a realy stupid question but is the dual exhaust advertised on Stillen's website considored a dual catback exhaust?
And I was also wondering, would the nissan dealership place that exhaust on without voiding the warranty? I know they wouldnt do the stillen Cat Conv w/ out voiding it because they arent street legal in any states rite?
Thank you so much for your help haha I feel kinda noobish:ughdance:

Stillen's exhaust is not a dual exhaust. The reason being is that the y-pipe forces the exhaust to flow into one pipe for a brief moment in time. A siamese x-pipe or h-pipe allows the exhaust to flow in their own pipe for the full length of the exhaust. The x and h connections typically result in better exhaust scavenging which equals more power.

Now, a true dual exhaust is an exhaust with two completely independent pipes without any sort of cross connection.

I honestly couldn't tell you if a Nissan dealership would void your warranty if they installed an exhaust. They need to prove that the aftermarket part caused an issue to void your warranty (Moss Warranty Act) which is highly unlikely of any cat-back exhaust.

thank you, so would the stillen exhaust not be the best way to go then?

DDMotorsports will this be the week?
