I recently replaced my flowmaster mufflers with Hooker Super Competition Max Flow Mufflers for my 318 Barracuda.
I like the Hooker mufflers much better than the flow master ones. I'm going to get another set for my 1974 Barracuda 440 build. I'll post a video of the 440 in a few weeks.
Here's my 318 with new hooker mufflers, 2.5" X pipe, tti long tube headers, 600 cfm holley, eddys performer intake, 302 closed chamber heads, & Lunati Voodoo cam:
