Review on 🏎️ Dynomax Ultra Flo 17221: Enhanced Exhaust Muffler Performance by David Carmody

Revainrating 5 out of 5

Great sound with no hum

They are nice, I have a small block 400 with a soft cam in 63 Nova SS, they sound amazing, I had hooker areo chambers, the drone was awful, they don't have a drone with me side pipes, also good quality. I would wholeheartedly recommend them for an old street car where you want a raspy sound with no rumble.

Pros
  • SUPERIOR PERFORMANCE -- Straight-through design provides unrestricted exhaust flow and reduced back pressure; Dynamic flow proven to reach 2200 scfm
Cons
  • Something else
