My current muffler is left over from the dual exhaust set up and is a Magna flow probably designed to make a bit of noise but I have a long round muffler I used when doing the brake in procedure out of the truck ,I will install that and replace my whining rear end in the spring and hope for the best .
I have until July to get it dialed in to go to The event in Tennessee , if this don't work ,maybe a radio and some head phones ?????

good planning is no substitute for dumb luck
