Took about 45 min to install sounds great I noticed the suction it has right away would buy another for my Tahoe

Installation couldn't be easier. 4 bolts out, 4 bolts in. I reused the stock bolts as they were the same length as the ones which came with the spacer. I have gotten a .2 mpg increase with the spacer installed and have noticed a slightly quicker throttle response.
