buzzing after header install
hey guys wats up...got a quick question....i got my ss autochrome headers installed with the comptech catback exhaust.....it was great but after one week of driving i noticed a buzzing sound when i first pull off.....when i start to step on the gas the buzz goes away....
can it be that the bolts need to be tight again or us something touching
anyone out there had this problem...i did a search and found some issues, want to see if anyone had them latley
thanks

I had the same thing.
Turned out the 02 Sensor and its washer were just sitting in the bung, even thought I had tightened them down. Stripped the 02 Sensor, but forced it back in If its the washer, add another or 2 to fill the gap. If its the entire o2 sensor, fix it or prepare to have it get worse and sound like a bee hive when you idle...mine did.

I will take a look at it today.....how do you know if you have resonance? and it was fine up until yesturday, i took a long drive to PA so that must of broke everything in.
i will re tighten the bolts
check all the hangers
also check out the heat sheild
will there be any cons if i remove the heatsheild, has anyone done this?

Wait about a week after initial install to re-tighten everything. This lets everything kinda get set and settle into place, then you will be able to tighten the bolts down even more.
The obvious con of taking off the heat shield between the cat and car is the heat not being able to disperse throughout the heat shield. The heat coming off the cat goes straight to the bottom of the car. The cat gets pretty hot, but I don't think hot enough to do real damage unless you are at the track for a few hours or tearing up the streets and then I don't even know.
Someone said something about a cat clogging because it was old and got hot enough to catch the car on fire because there was no heat shield. I think this was an extreme case, but just something to throw out there. It may have still caught on fire with the heat shield, you never know.
Kind of OT, but how long are catalytic converters supposed to last you?
Good luck and I hope the resonance stays gone

I know ppl disagree but this is what happens when you buy $100 headers. Some are alright and some are not. It is made with cheap material and therefore you get resonance. For $100 you got a V6 header; that's a crazy price. But you will have to live with the cheap header cons: thinner steel, resonance, cheap hardware, decent fit, possible uneven flanges (that is why they include a thicker gasket).

I have noticed some of my bolts backing themselves off as well. I went to tighten everything back a week after first install, and then again after a few more weeks and it seems every time I get in there, a couple (the same ones every time) of the bolts are loose again.
Should I use some kind of chemical on the bolts to hold them in there better?
How hard will it be to take them off if I need to if I do put something on them?
