Sounds more mello after a week of daily use
The installation: Def could have been easy if they had included a left and a right muffler, as each muffler is specificly left or right. I received two driver side mufflers, resulting in having to cut off the mounting tabs and reweld the tabs back on. That makes this a non-bolt on system. The mufflers can not be flipped as the inlet is 3" and the exit where the tip mounts is 2.5". Sound:These do drone, but not as much as flowmasters. Also seem to have gotten quieter after a week of daily use.
If you want loud ..... this will do it
Installation took about one hour as I had to cut off pipe for SWB truck. This system is really loud ... too loud. I replaced the exhaust tip with a straight end and that helped some. In a few days I will have evaluated the performance vs fuel mileage and decide if I will keep this system on my GMC Canyon. At this time I am not recommending this system to anyone unless you are deaf.
