i just bought/installed a cheap ass ebay stainless steel header and downpipe. now my car makes this squealing noise. it usually depends on how hard i press the throttle and i usually begin hearing it about the same time i hear my short ram growl. it does however start to go away as i near redline. wat is this? it almost sounds like a belt squeal, but i know its coming from the exhaust. i also have a gutted cat... so wat is causing this noise? anybody with a similar problem?

wat would adjusting my idle do if it does this while i'm goin down the road? and i just replaced the belts.... they're new... i swear its comin from my exhaust. it just sounds like a mix between a rattle and a squeal, unlike anything i've heard come from an exhuast b4.....Comment

Try tightening all the exhaust bolts again. Maybe you're getting a little vibration stress or rubbing somewhere.Comment

thats almost wat it sounds like.... but i know its not rubbin, and wouldn't it leak if it was loose??? thanx for the help btw... this is annoying the shit out of meComment

It might not be leaking enough to tell. Try tightening everything up, check to see if it's rubbing or touching anywhere, and just for kicks, check your belts.Comment

sounds like a plan
thats wat i was goin to do anyway, but was just lookin for suggestions

When you put all your bolts back on the header, did you use thread lock? It might be leaking just enough to make the noise you hear.1990 LX Coupe-----1992 LX Sedan

usually with ebay headers, you'll notice some vibrations around 2-2.5 rpms. I think its because of the poorer quality and manufacturing of the pipings. And if the squeal is actually more like a vibration then I think a possible cure is to heat wrap the header. Or beat yet, save up more money and buy a DC or one of the better name brand. Have fun!Comment

i have a whistle at about the same time, depending on how hard i push on the gas.. and just before the short ram grumbles.
and i also have a vibration/rattle at 1750 rpms.
but i have a stock exhaust header
mines from my short ram..
im sure of it

its like a whistle/squeal/rattle... lol hard to explain.... excuse my stupid question, but wat does thread lock do and how would that help? i was also begining to wonder if thats just the way they sound. a musical instrument makes noises when you blow thru tubes, maybe it was just the way it was designed and it makes noises as air passes thru it
