2009 V8 Colorado Aero Turbine Start, idle, rev
http://www.V8ChevyColorado.com -- check it out! My new 2009 Colorado V8 Sport, revving with the new muffler - AeroTurbine 3030XL and a 3.5 inch Magnaflow tip. This is the day it was welded on, and the truck only had about 175 miles on it. So it'll sound different with time.
2011 Colorado V8 Flowmaster Exhaust
40 series delta flow muffler. 5.3L V8
FlowMaster Super 10 after swapping from a Super 44, Canyon-Colorado 5.3l V8
Super 44 was not quite what was hoping for in terms of deeper tone and loudness. Has a MagnaCharger installed, both types still produce compressor sound at WOT.
