New owner/member, 2-3k rattle question

Hey,

I'm new here and just got a '98 prelude SH last week.

Normally i am into 4-wheeling and older landcruisers but i need a fun DD so i got the prelude.

The P.O. put on an exhaust, intake, coilovers, and few other things.

Here is my question though. After about 5-10minutes of driving i notice a very very annoying rattle in the 2-3k rpm range. At first it definately sounded like a heat shield of some type.

I looked around myself but could not find anything. IN the last 4 days, 2 shops have taken a look at it and cannot seem to find out whats going on. It sounds like metal of metal rattling. Any advice?

Lastly, if it helps at all, the motor has 96,000 miles. Is there anyway to determine if the rattle is internal? although it doesnt sound like that at all.

Heat sheild around the exhaust. Get under the car when it's cold, and punch the exhaust until you find the rattle. Fixing it could be a little harder though.

I had a similar situation when I brought my 98 lude. Found out it was actually the cat and not the heat shield. So I just brought a high flow cat instead and now the problem is fixed! =) Hopefully it helps.

It has an aftermarket header, i'll see what i can do about just pulling the bracket. See if that works without causing any issues.
