Tony/Will/anyone who has (or had) the Berk HFCs...

I seem to have a "rattle" noise at ~3k. Has this ever been an issue for you? They were just installed today and I didn't notice it until after I had driven for several miles.

Ideas?

 

it seems to be anything within the 3-3.5k range, going up or down...

 

Is it a rattle or is it like a squeeking noise???
Does is sound like metal and metal rubbing against each other???
I installed my test pipes and i have the same problem... There is a metal shield i guess you could say that looks kind of like a U that protects the O2 sensors... It is held by 2 bolts, but in between the bolts there are some rubber washers and i guess if you dont put them right the metal will rub against the car metal and it will make that sound????...
Im almost 100% sure thats what it is..
I have not had the time to take it off but tomorrow morning i will... I will let you know if that fixed it !!

 

it is definitely a metal-to-metal sound. i have heard that some people have had the same issue, but that the problem was the stock heat shield.

if you fix the problem, let me know! thanks man.

 

Nope.. I haven't heard this w/ mine..

 

well, i'm going to take it back up this friday to have it looked at. i'm convinced now that it's the heat shield, so we'll see if that fixes it. the sound is INSANELY annoying now...i can't give her any gas at all without sounding like a turd.

 

well i found what it was... It was that metal i was telling you about...
Here is a pic of it and also a pic of what it was rubbing with...
The corner of it was rubbing against my test pipe were the O2 sensor goes...
I just took it off and OMG i wana drive my car everywhere LOL
Hope that helps and sorry for bad Cell pics...

 

hmmm interesting. i have since taken mine off (since Cobb and myself could not figure out for sure where the sound was coming from). the guys at Cobb are convinced that the noise is coming from the flex joints in the Y, but this is an interesting theory.

really, i'm sick and tired of running back and forth up to Cobb, so i'm going to see if i can find a way to get the car up myself and see if i can give it a go. not sure if/when i'll be able to do it since i lack the proper tools right now, but we'll see.

thanks DC for the heads up, i'm glad you got your test pipes workin.

 

You might be able to do it if you raise one side up MAYBE...
and its only two bolts you have to take off...
GL dude!!

 

Yeah... Mine were installed in the back of a house w/ just a lowered jack.. That's all you need man.. You only have to lift one side of the front of the car as you go..

 

VV, you can borrow my lowered jack, n even my jack stands, if you like.

 

thanks yash, i might take you up on that. i know that the bolts will definitely not be a problem coming off since they have been off and on so many times over the last few weeks.

if anyone would be willing to lend a hand and/or expertise, i would greatly appreciate it. i'm in no rush at this point since they let me down the first time. a man can only take so much disappointment...lol.

 

^ If you got the tools to take that piece out I can lend you a hand.

 

thanks for the offer yash - however, i'm gonna take it up to Dick Wong this friday and let him take a crack at it. he did tony's berks, so hopefully he can hook me up.

i'll keep you guys posted with what turns up on friday.
