freeking rattle

[Pandemic]

So... Im pretty sure that the mechanic that did my headers is a friggin idiot. It rattles at about 2k revs. it looks like the downpipe/flexpipe is what is rattling. Any suggestions for this? I was thinking maybe some of that heat tape would atleast deaden the sound a bit... it's annoying.

Take it back and tell him to do it right.

Is the sound coming from the flexpipe area? If it's right beneath the firewall - maybe the guy had to bend some heat shield and its contacting now, or one of the fasteners broke off. Mine does that, too, before and after the engine swap. Bleah. I hear cbs doing the same thing once in a while.

Just make sure it's not coming from the engine itself. Hope this helps!

check for atleast 1/2 to 3/4 inch clearance around the exhaust pipe. ie: on a cool/not been run engine, see if you can fit you hand around the exhaust. like to about your knuckles. if you can then thats good clearance. if not then check for bent heat sheilds or somehing else that it could be touching. good luck in eliminating the rattles

i just recently had a 2k rpm rattle also. turned out to be the bracket that bolts the downpipe to the block that was broken into 2 pieces causing the metal to bang against each other at 2k rpm. check to see if it's either a) broken and making contact w/ each other b) bracket bolted to block, but not downpipe causing it to rattle against the dp itself

otherwise i would check your heatshields for loose bolts/bent portions

yeah i had this prob. too. On your downpipe, there is a tab that's supposed to bolt up to the engine somewhere, well mine wasn't exactly tight and every now and then when idling or going up to 2k rpms, it rattled. So i just cut it off. It really is not needed, since the header is bolted on the engine w/ 9 bolts and is held up also by the cat converter. So do what i did and cut it off, it'll make life easier, trust me.

I'll probably take it to the garage where i had it done... let them figure it out. Ugh - I hate other people touching my car >:C

[kmartxxx]

yeah man check to see if the guy put the bracket that connects the pipe to the block i figured its wasnt needed when i installed my header and after had the rattling noise and yeah it gets annoying as hell

[cp[mike]]

rattle or knocking?

what kind of header?

ebay headers like to come very close to the front crossmember, its possible that its bumping into that.
