I dunno if its the SRI or headers...but when I start the car, there's a slight boom and the idle at drive is like a rattling sound. Bad? I re-installed the stock intake after this and the problem persists.

Help?[:@]

 

No?

 

Is it because I removed my resonator?

 

A boom? Like a bomb going off?

 

Not that loud...but what the sound of an aftermarket exhaust sounds like. It's a very deep tone.

How about the rattling when I'm idling?

 

I don't have that sound and I have a sri. Is your header bolted on tight?

 

Checked that. I tightened them up yesterday, sound still persists.
