I've noticed an increased rumbling after installing the Alta intake. It's especially noticeable at low rpm's. I think it's the exhaust because I can hear it coming from the rear when I gas just a little bit. Anyone else notice this? Could the exhaust be loose? Or could it be the increased airflow? Any thoughts? Thanks!

 

Stock or aftermarket exhaust?


I have the alta and stock exhaust, and noticed no rumbling or idling difference.

 

Is the heatshield for intake in tight and the hose on good. Otherwise you might just be hearing the normal intake sound.

 

I have a stock exhaust. The heat shield looks to be pretty solid. I did lose one of those rubber grommets that hold up the air box but it still seems pretty solid. I have a replacement that I'll be picking up this week.
