The best is yet to come. You can't get any kind of idea what an exhaust system will sound like until the exhaust gets a good four or five thousand miles on it. The top muffler out of any other muffler made is the Dyno Max 17749. This muffler has gone through more tests and has passed with flying colors.
I have about 17,000 miles on mine now and wow does it sound fantastic! Crusing, it reminds me of our Chris Craft ski boat we had back in the 60s.The boat had a 348 police enforcer motor that was out fitted for a boat. My el Camino has a 454 truck engine. So while its not a race engine, it isn't really stock, since truck engines are built to rev while keeping a strong torque band.
Mine didn't sound too good with the X pipe but once I removed it, that great big block, Duntov Chevrolet sound came back..
