Installed the intake elbow on my lly. S&B intake elbow. Everything came off fine. Was a tight fit but finally got it positioned. Now I hear like a growling noise. No change in turbo whistle which is no big deal. Everything went back on fine just struggled with the elbow getting it to fit in. Just curious to see if that's normal.

When I put the S&B mouthpiece on my truck I noticed that the sound did change slightly. Not so much a growl but just seemed a bit louder, maybe a little more turbo whistle too. Is the noise coming from the engine compartment?

Sorry for the late response. But yes I can hear it in the engine compartment. It's not loud but it is noticable. And only at idle. Park or at a stop. Doesn't sound threatening but it is a different sound and not one I was expecting. I did read up and saw that more whistle sound or a slight loudness in exhaust. Again just not what I was expecting. I did check the elbow. Everything seems to be correct.
