Just playing around with my Impala right after I had the gears changed from 3:08's to 3:73's. Also had the Eaton Tru Trac installed for the differential
It already has the K&N Intake, Full exhaust with Flowmaster mufflers and the Clear Image Automotive Headers.

My lovely daughter filmed this for me with my Canon T7i.

I stink at doughnuts. Looks like I need more practice.lol
