Review on Dynomax Ultra Flo 17229: 🔥 Unleashing Power with the Ultimate Exhaust Muffler by Gregory Shorunov

September 23, 2022

Good road volume at idle and cruising speeds.

I mounted them on my 72 Nova with an 11:1 SBC 406 that goes up to 6500 rpm. At idle and while driving, they sound harsh and deep, but not unpleasant. At wot they will let the engine breathe freely and wake the dead. :-D

Pros

Muffler

Cons

I vaguely remember
