Pontiac G8 V6

Reviewed By Joshua M (TOLEDO, OH) Reviewed for a 2009 Pontiac G8 —9/21/2017 7:39 PM

Installed these on my Pontiac G8. The exterior sound is a nice rumble. not too loud, not too quiet.The interior noise "drone" is rather noticable but not too terrible and has a little vibration to it. Again, not terrible. Nothing a little sound dampener cant fix.

Reviewed By Louis G (GREENVILLE, SC) —12/14/2017 4:03 AM

I was looking for something to make my car pop a little more. I'm completely gutted and all components have been changed. I went from a 3.5 to 2.5 exiting hole diameter. It pops but not as much as I was hoping for. But overall sound quality is nice. Doesn't sound ricey. Good for what it is.

I purchased a new intake the same day and the two of them together make the car feel and sound great.
