Weird noise, anyone have similar experience?

azn370z · 05-25-2012, 12:15 AM

I've had my z for over 2 years and 20k miles. I have stock cats but berks cbe.

I know what the sound of a screw in a tire sounds like. I know how the brakes can make a clicking sound if there's rust from moisture.

I left work, no noise while rolling through the parking lot. Once I got onto the road I heard a noise that is hard to describe. It sounded like a metallic sound, maybe the sound of something dragging, maybe something in my exhaust, or maybe something rolling in the barrels of my wheel. I think the speed of the noise increased as I drove faster. I believe the noise did stop but started up again as I drove. At one point I thought I heard the sound of gas coming from my cats. Once I got on the highway the sound disappeared.

When I got home I did a visual to see if my exhaust was loose or anything in the tires, and rotors.

So anyone have a similar experience or know what happened?

Berk cats have been well known to be junk and blow up. Parts could have broken off inside.

I don't remember the setup of the Berk from pics but check the heat shield near the cans in the back...I had a similar issue when I had the invidia installed and the bolts were just hitting up on the heat shield...made a sound like change dangling around in a metallic can or something...comes and goes with expansion of metals due to heat and highways speeds/noise

Oh no, another incident involving Berks!

This is a sign to stay the F away from Berk.

I don't see why people are slamming Berk already? I have the CBE on my car and it's been nothing but wonderful. Perfect fitment, no issues at all for me... He hasn't even said he's verified it's even a problem with the Berk?

lol @ blows up.

My Berk CBE is perfect still -- I have about 24,000 miles on it.

azn370z · 05-25-2012, 12:38 PM

I haven't heard the noise since that one time. I'm going to put it on jack stands and take a look. If I find anything I will let everyone know.

Until this morning I'd never thought about bashing Berk's.

Since I have another brand, it must be time to bash your brand.

What would make a HFC or CBE explode or blow up (short of explosives) anyway?

I probably am totally wrong, but do your brakes have a wear indicator? Many times it sounds like metallic scrapping/scratching.

RandyD · 05-25-2012, 05:04 PM

yep - i thought brake noise based on the description.

azn370z · 05-26-2012, 02:22 PM

I took a look underneath and didn't see anything. I don't think it's the brakes since they have a lot of life left and it only made the noise that one time. I'm thinking a pebble was stuck to the barrel of a wheel, then as I slowed down it shot out of my wheel and rolled toward the front of the z making the hissing sound. I think the berks cbe is fine, but their Hfc is something I wouldn't trust using.
