well i have an annoying problem, at 1900 rpm, i have a rattle, sounds just like a loose heat shield, but before 1900 or after it doesnt make it. Ive heard it at 3200 a little as well. I checked all heat shields i could find, and the cats seem sound.....do you guys have any other ideas on what to check?

 

mite just be your exhaust pipe rattleing against the frame i had same problem so i just tied them down and problem fixed

 

alright thanks

ill take a look

 

mine makes the same sound, I thought that it was a pinging noise but maybe it is hitting against something...

 

Same here! we need to figure this out before i go nutss
.

 

i thought it was because of my exhaust, but i had it on a while before it started
