BERK Catback Exhaust System installs/reviews

azn370z · 06-28-2011, 01:03 PM

Anyone having issues with vibrating noise? I installed these myself about a year ago and recently noticed noise after 4k rpm, almost sounded like I have a engine in my hatch. I took a look yesterday and saw the heatshield was very close to the pipe. So I bent the shield. I took it for a spin and didn't hear the noise at 4k but not sure if the noise came back higher up since it gets really loud.

I'm still enjoying the cbe, was thinking of switching cbe but after spending time underneath my z i remembered how I dread working underneath it.

Thus far no problems...Still sounding as good from day one...The only sound/vibrating I hear around that RPM range is the imfamous "Hiss" on deacceleration...which is noticible since I have the HFC's.
