Went on EASY. and I love the sound of this exhaust on my truck. Lower mid range tone. It is pretty loud though.

This is nice, not too loud, a good deep tone. It gets rid of the old dual exhaust in 2.25 tube...my mileage actually increased pulling our fifth wheel.

I have this on a 05 silverado 2500hd crew cab with a 6.0. Sounds very good, it is not a high pitch exhaust, very deep tone, the drone is not bad at all, which some say is horrible, I would recommend this product for a happy purchace

I was running a Flowmaster Super 40 dupping rigth at the end of the cab and it sounded good but when I put this Dynomax in, I had a shop weld the whole thing in and I'm starting to set cal alarms off again. I couldn't be happier with this exhaust, its got a nice low rummble at idle but when you get on it, it loud but not too loud. If you're looking at getting this, get it you won't be disappointed.

Pretty easy to install, getting the old exhaust out was the hard part. It is pretty loud compared to stock.

This cat-back exhaust kit was super wasy to install, took an hour. Sounds great in town cruising speeds and not real bad on the highway.
