Just need to know if scraping issues might occur.

Lastly, are the tips (both left and right) centered to the cutout? In looking at the picture, it appears that the side-to-side width of the left-and-right tips are a tad narrow.

Thanks.

After my installation (sorry, no pics) there doesn't seem to be a difference in clearance. I was a little worried looking at the angle of the pipes while the car was up on the lift, but it looks like nearly the same clearance as stock (from Nismo, not base).

The tips on mine are also near-perfectly aligned from right to left with the Nismo's exhaust "cut outs" of the bumper. I imagine the base will be the same.

That was the best i could do since i don't have any tools to properly bend it.

As for the lic. plate being crooked I did that on purpose to make an optical illusion that the exhausts weren't crooked.

lol, good idea with the 2x4, i think mines are crooked too.

Berk Xpipe installed, no issues at all, pipes line up perfectly, the sound is unbelievable, no drone, you could pass a cop with this exhaust at 2500 rpm and he wouldn't even blink. God forbid you did that at WOT.

I am posting a couple of pics in the official Berk Xpipe thread.

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.

i finally opened my box up today (received it last tuesday). everything looks good soo far, everything was in there from what i saw, im just hoping nothings bent. im gonna be doing the install in a couple of hours, i hope everything lines up well. super excited.

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

MightyBobo · 03-20-2010, 07:08 AM

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.

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!
