if i'm at an idle, at about 3000 RPM's i'll hear rattling. same goes when driving...but with the stereo up i try to ignore things like that...

can a rattling heat shield be fixed to not rattle or is the only remedy taking it off?

or am i hearing something other than the heat shield?

 

could be the downpipe.... i'd check under the car at idle... see if its louder inderneath or if its louder in the engine bay.

 

3000 RPMS isn't idle.....

and just take it off if it's rattling, or tighten the bolts

 

my bad... read it wrong

 

when i said "idle" i meant not driving

AKA.... revving

 

Just take it off.

I had mine off for about 3 months before I got my header.

 

Are you sure it's your heatshield ??? It could be alot of different things.

 

i think it's the one under the car... in between the chassis and exhaust pipe. ya know?

 

I had that problem with my 90 beretta. It hung down like 2-3" from the car and would scrape on everything.LOL

If you hit bumps and it makes noise, definitely the Heat Shield, but other than that I dunno take a look under your car and tighten or rake off the noisey piece.

 

here's what was rattling:

the heat shield protecting the #2 catalytic converter. Hyundai Part # H2UU15

Just ripped that sum'b**** off and all is betta 8)
