Maybe I am missing it, but what was it that you found? Was it simply the flexible joints?

They probably don't want to tell

Ahhh I'm at work and can't see the pics...DAMN!! I'm pretty stoked to see how this all pans out. If it yields the same or more hp as Stillen and sounds deep without any drone or rasp, I'm going with Berk for the CBE and HFC!

How is the weight of this exhaust adding up? Slightly less, significantly less?

Darn was hoping for the \/ type muffler position out the back for that aggressive look.. Other makes are doing it? Maybe I'm confused.

Yeah I think GTM is offering that configuration.

I personally like the parallel setup, so I'm still all thumbs up!

+1, plus its a bit more aerodynamic than the \/ setup. The \/ setup essentially makes your rear bumper a parachute lol. Not saying that the parallel setup is crazy aerodynamic, but its more so than the \/ setup. Every little bit counts

Some more photos from Berk! Mock up version is done! The production version will look largely similar except its my understanding that the hangers will be re-worked a bit to look better and obviously the bracing used to hold the exhaust into position during mock up will be gone. And I believe we will still be testing true dual/X-Pipe/H-Pipe configurations later on.

and I j**z in my pants

Hmm this is interesting. I like the fact that they're putting flexible joints in the Y-pipe like stock, that's got to reduce the resonance of the whole thing, which I suspect would make for a cleaner sound. The lack of any sort of crossover between the sides seems odd to me though. I thought there were usually benefits to having some variety of crossover configuration, even on a V6 application (although not nearly as necessary as on a V8).

They are going to test this configuration, X-Pipe, and H-Pipe. They just haven't gotten that far yet.

Yeah sorry I failed at reading through the whole thread first

I'm sure Berk doesn't want to tell everyone their secret but I don't care. I just don't want my exhaust bouncing around on every piece under the car.

Minicobra1 · 05-15-2009, 05:22 AM

Hey Mike, I visited your car yesterday, the bimmer needed some lube

j/k the exhaust is looking good man, cant wait to hear what it sounds like
