Buzzing sound

My car makes this awful rattling sound just when I'm about to change from first to second and sometimes in second. I'm preety sure it's my heat shield rattling against my header. Anyone have this problem in the past, if so how do I fix the problem?

i have the same kinda problem but the inside of my cattelatic converter fell apart and it just rattles all the time inside it

well if it is a heat shield most likely it broke off from the mountings, so you'll need to buy a new one and just mount it up.

Have you fixed it yet or do you have to buy a whole new cat?

i just deal with the noise, if u think its the heat shield u can put metal pipe clamps around the heat shield and cat heres where ive seen that idea heres where i got that idea (http://www.fourthgenhatch.com/index2.html)

Thats a preety cool site. Lots of info. Thanks

Wow! My exhaust has been rattling right around 3,000 rpm for a long time now! I'm fixing it this weekend!
Yee-Haw!
Oh, yeah, if you've got a bunch of hoseclamps laying around, you can always combine multiple clamps to make one BIG one.

My exhaust rattles around 2-2.5. What is this?

ON that sit he said he got some performance gain from this? Can we say BS.
