Muffler options ?....

I basically cloned a 380 Magnum crate engine . Tried the Heart throb 2.5 " exhaust , modified it , to fit. Loud as hell with the supplied Imco turbo mufflers , and turned down at the axle. Adding a 3500 stall in the future , will make it noisier . Need muffler recommended , 2.5 " pipe, axle turn downs
