Hey guys - here is a quick video with some low rev (2000 rpms since the engine was still cold) of the eBay cutouts I just installed. The car has a stage 2 TSP cam and long tube headers with offroad connection pipes. The mufflers on the car are GM Performance and I have the stock 2.5" mid pipes still in place too. From a pure sound perspective, in my opinion you can't beat having electric cutouts paired with some quiet mufflers. It is so awesome to go from a quiet sleeper to full out race car with the push of a button.
If you aren't interested in the install part, fast forward to the end to hear the results.
