2000 F250SD v10 with Flowmaster 70 series and dual turn downs

2000 F250SD v10. Stock cat, changed y-pipe and Flowmaster 70 series( 3“ in & dual “ out). 3“ stainless turn down tips. Very quiet but still has the hair dryer sound under load. I have tried different configurations to make it sound good but anything louder sounds like a huge hair dryer.
