2015 Silverado Muffler Comparison Part 1 Updated (Cold Start)

This is a compilation of all the cold start clips that I have recorded of the various different mufflers I have tested on my 2015 Chevy Silverado with the 5.3L Ecotec3 engine.

The truck is equipped with Kooks 1-3/4" long tube headers with catted "Green cats" y-pipe into a single 3" pipe out the stock location with a 3.5" slant cut tip. Each muffler was simply clamped in place, run for a week or so then switched out after the videos were shot. No other modifications to the exhaust were done besides the dual tip change later in order to keep consistency in highlighting the sound differences between just the mufflers themselves.

Each muffler has its own separate videos that can be viewed by checking out my channel.
