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.
