True dual please.

nice updates guys...

hey berk, how will you guys know which setup to use (true dual, h-pipe, or x-pipe) what will be the deciding factor?

will you guys do mock ups of all three types and dyno each to see what gets the best results?

+1. I hope Berk ignores the hype and simply goes with whichever design yields the most gains. I'm ready to try something new (if it gains more than the Stillen).

When I finally decide which exhaust to go with, gains will have been the most important factor for me. Hopefully they can do some HP magic and given Stillen a run for their money. Competition breeds excellence

When I say true dual I mean two dual pipes with no interaction between the two. The deciding factor on which one we will produce will be power production & sound. The exhaust will be a dual 2.5" design. That picture of the front section of the exhaust is two separate pipes, the rear of the car will use two separate mufflers.

Adding an X-pipe or balance tube will usually GAIN power and reduce sound. At worst they will have no effect on power but will help to quiet down the system.

Solismo - 90% of our 370Z will transfer over to the G37. Once we finish this up we will jump right into the G37.

LiquidZ - What you see in the picture is a mild steel prototype. Nobody prototypes in stainless because of all of the material that we scrap in the process.

Semtex -We would love to do a back to back comparison.

SOLISIMO · 05-06-2009, 01:37 PM

Any word on a G37 exhaust ?

LiquidZ · 05-06-2009, 04:25 PM

I'm fairly confident Berk will match if not exceed Stillen.

RCZ · 05-06-2009, 07:07 PM

Make it loud

Im awaiting the results too

semtex · 05-06-2009, 07:10 PM

I want it to sound like the SACLAM exhaust.

RCZ · 05-06-2009, 07:14 PM

I'd prefer a higher pitched shriek than a lower grumble...

semtex · 05-06-2009, 07:31 PM

I just want my exhaust note to make babies cry. I was parked next to a car yesterday where this lady was strapping her baby into the baby seat. I fired up my Z, and the baby didn't cry. That's just wrong. (j/k - sorta)

I want people to have to cover their ears when I drive them

DannyGT · 05-06-2009, 08:16 PM

I had one of THE loudest exhausts with my scooby, I mean I loved it, it was brutal in the best way possible but you know what I'm done with that...if it sounds smooth and euro like the AMUSE exhaust I'd be happy.

Exactly. I want smooth, loud and high.

PS: Did you have a nur spec?

I had an invidia G200 on mine

I feel ya. I had the Topspeed pro-1 on my 350z (If any of you are familiar). It was way too damn loud. The drone would make your internal organs vibrate. I switched to the Nismo after about a month.

Don't get me wrong. I love loud but it's gotta be the kind I can live with on daily basis. Maybe the Berk will be a perfect balance.
