I purchased this Gibson Sport exhaust because it claimed to have a deep throaty voice and NO DRONE when driving down the road. What I got was an exhaust system that sounds like I have a hole in my pipe before the muffler of a stock exhaust and the DRONE inside the truck is so loud and annoying it gives me a headache if I drive more than a half hour or so. Needless to say I will be changing the exhaust system.
Not a "bolt on", but nice setup.
First off, instructions say "bolt on", this does not "bolt on". You will need a hacksaw and some automotive knowledge. It's easy, but that needs to be known. This exhaust sounds great without being obnoxious. I was eyeing some cat back systems but have read a lot about people having drone issues due to the MDS so I opted for keeping the stock "briefcase" under the truck. Installed in about an hour or so. Measure twice, cut once. All in all I really like this setup.
