does anybody have this problem too it only rattles at about 2500 -3500k and that sucks cuz thats what im usualy on when driving and it sound like crap.. i thougth it was the heat sheild but it wasent. any suggestions on where this noise is coming from... by the way i have a 1995 acura integra gsr.. thanks in advance

 

if you didnt find da problem check da headers or your head on the car maybe da valves

 

if its not your headers it probally your valvetrain. when was the last time you got your vlaves adjusted??

 

i would bet that its your heat shield. and your car doesn't have multiple headers, it has one header.

 

chnage the header, make sure you put that header heat shield on, it will melt the radeatior connector for sure.

 

Funny story my friend and i were having the same conversation last night and we couldn't find out what is was it was late so we said screw it and he left, this morning he called me and told me that he had blown his piston rod through his block on the way to work.

That was a little off topic but do you know where the noise is coming from?
head,block.heat sheild, manifolds.

 

i had a probelm like that but it was around 2000, it could be you exhaust, my car is lowered and i would scrape against the pavement every now and then, then i realized that my exhaust pipe split right after the resignator, so maybe theck your system to see if it split anywhere

 

I have a rattle noise from 2-3k too. I know for sure its inside my cat. I replaced my aftermarket header with OEM and there rattle is still there. I'm just too lazy replace the cat

 

im pretty sure it has to do with my header or exhaust system because the noice is cleary coming from cat or sumtin down there and no theres no split in the piping...

 

There's multiple heat shields all along the exhaust system. It's very common for all of them to start rattling over the life of the car. Unfortunately, you just gotta get under there and check one by one. Or, if you're brave, get the car on four jack stands and crawl underneath. Have a friend rev to approximately 3k, or wherever it makes the noise.

 

i have the same car and i had the problem, i found out that it was the shield on top of the catalytic converter. ripped it off and checkmate!

 

heatsheild

 

Mine made noise where the secondary o2 sensor comes out, the connector below the shifter poed out and was banging agains the heashield, pissed me off long time.

 

just check your heatshield thats probably what it is

 

i have the same problem right now but i dont mind it, im so use to it and plusi always go out and race its nuthn to me

 

Make sure the entire exhaust is secured with the necessary springs bolts. Meaning don't only have one bolt on a flange that requires two bolts because it WILL rattle. It sounds like your bolts aren't tight or you are missing a few. Check that and get back and let us know what it was.
