Review on ACDelco 540 347 Original Equipment Monotube by Carlos Burrows

Holy smoke what a great ride. When my wife and I bought our Rainier it ran into some aftermarket shocks and rode so hard I hated riding it. Having had a Rainier before, we knew the ride was going to be a lot better than it was. So I found out what the original part was and it wasn't a regular Chevrolet or GMC muffler, it was a Rainier muffler. It was an easy install, easier than changing brakes, about as difficult as changing a tire. Definitely worth the money if you want a quality ride. If I had a Trailblazer or Envoy I would install them too.
