Hey Mike, I can't dyno the exhaust due to technical difficulties, have you or anyone else been able to get baseline numbers on HP gains with the catbacks?

I haven't seen any new ones yet since the ones I did way back when with the prototypes.

Yes, the HFC/Cat-Back combo made 36whp on my car. I didn't test with the stock cats.

Just got mine installed today...fitment is perfect and it sounds awesome.

Figured I'd chime in here - PM-ed Berk too, but who knows, maybe someone else ran into the same issue.

So vertically, my tips are lined up perfectly. But the whole rear section seems shifted to twords the passenger side a bit. Any theories at all? Maybe just loosen all the bolts and try to realign it all? I didnt see anywhere in particular that it might have been misaligned...but hey, you never know right?

I think the only way to shift left to right is by adding another gasket. Call berk and I'm sure they will send you one. Hopefully they sent mine out.

How far were yours off? I may need 2 I think, at least - an additional one for between the HFC's and the Y-pipe, and another between the y-pipe and the extension to the passenger side of the muffler piece.

I easily yank the exhaust to the left and that centers it no problem, but as soon as I go driving it shifts back over again. Hmpf.

Yeah, there is no point trying to push the exhaust into position, the only way to align it is by bending the hangers. I'm not sure how well the gaskets will work but I'm pretty far off.

so just wanna give a real quick brief review on the berk exhaust. ive had it on for about 3 days now. and everytime i know im about to drive my z i get really

the z definitely sounds soo much better now. the sound on start up is amazing, then it starts to quiet down when it gets to idle. i guess these engines are just quiet in general because whenever its idling, it's reallly quiet. but once you start getting on the gas and going through all the gears, it REALLLY opens up. sounds sooo damn nice. its like a nice deep growl. no rasp at all. definitly a great sounding exhaust. and all i have is the berk cbe installed. and i plan on installing my fast intentions hfc's soon.
the exhaust is definitly well made. pretty nice welds. mine was a little misaligned at the tips. but i just used some force and aligned it as best i could and also bent the brackets that hold the hangars. and i made the tips align perfectly, the exhaust looks as if it came stock on the car... which is what i was going for to begin with. theres no rattles or weird noises, everything sounds great. no issues whatsoever. im really happy with it and can't wait to open it up even more with the high flows!

Installed my Berk CBE on Friday with a buddy who drives an S2k...

Everything out of the box was fine, including how it looked while packed in the box. No huge holes or pieces all over the place while in side it.

I took off my NISMO exhaust in about an hour and then aligned the Berk on the ground and had no issues there either.

The gaskets for this guy were great; Nice and hefty, leaving little room for the chance of having an exhaust leak.

The Berk went on fairly "headache," free, other than some mild aligning with the muffler to it's connecting pipes (which I'm pretty sure I even had to do when I previously put the NISMO). I had no issues connecting it to my Berk HFC's, either.

Upon start-up, first there was this

then this,

and finally this,

The first thing my S2K buddy said, "ohhh, now I see why you wanted this exhaust... Can I drive it? I wanna hear the this thing synchro-rev match!"

On Saturday, I went on a run, up the local mountain (Mt. Lemon), that was being organized by some Honda friends and it was nice being the only Z out there and sounding bad-a$$, while getting the "wtf" looks and "is that the stock exhaust? it looks stock... Damn, sounds nice!"

It was a very gratifying weekend, in all, I must say!
