I ordered a Volant CAI for my 2013 Silverado 5.3 RCLB. I know intakes don't add much, if any horsepower, especially with out a tune. I was wondering if it would make my truck sound better, or at least louder. When I 1st bought my truck 2 weeks ago it was so quiet I had to pop the hood to make sure it had a V8, I am eventually going to install long tube headers and an exhuast, and eventually a tune. I'm hoping the intake will improve my MPG a little and make it sound better.
