I have 2-1/2" pipes from the headers back to Magnaflow 14" mufflers mounted about a foot behind the cab under the bed exiting behind the rear tires. It is too mellow for my taste at idle and part throttle acceleration but it gets pretty loud at WOT and high RPM. However, the Magnaflows sound like glasspacks to me when my 383 is turned up. I have wondered if turn downs would give it more aggressive sound or if i just need to change the mufflers. I have been listening to a lot of sound clips of Pypes mufflers in Youtube to get an idea of better setup, but i really dont like the glasspack sound these Magnaflows make and I have uswd Magnaflows before and they sounded better.
