If you like really loud exhaust noise then Gibson is it, looks good, fits real good, easy install, but it's so fricking loud, your neighbors will give you the stink eye every time you start it up. So I called Gibson an they said " that's just the nature of the beast" , well the web site says on a scale of 0-10 the swept side is a 2 ( 0 being stock and 10 being very loud ) that's BS , ( BTW once installed no refunds ) VERY LOUD!!!

Great look, Great sound, Very Happy

For an I6 trailblazer there isn't a whole lot you can do to make it sound "good". With this Gibson exhaust however, it sounds about as good as it can get! It also improves the look of the Trailblazer from the rear 100%. After immediately installing it, the sound was a little too loud and high pitch in the 1500-3000 rpm range for my liking, but after breaking it in for about 150 miles the sound has become very deep, has toned down a good amount, and has that distinctive Inline 6 sound. Many compliments on it so far, and I couldn't be happier with it's fit, finish and Sound now. Installation was fairly easy other than getting the old exhaust off which took some patience but after that everything went on smooth and fit 100% perfect.
