I received the exhaust two days earlier than promised, always a pleasant surprise from AutoAnything. I was going to have someone install it for me, but the instructions seemed so simple, I gave it a shot! The Magnaflow was easy to position with the truck's existing exhaust hangers. Reading these reviews was very helpful and encouraging. Considering my heat breaks from the scorching weather, I'd say it took about three hours to install by myself. Sounds throaty , not too loud, purred ECG..
