Dynomax VT® muffler, a revolutionary, high-flow straight-through stainless steel performance muffler that controls irritating drone while ensuring maximum performance.
Our long-suffering "05 F150 went under the knife yet again to give the DynoMax VT a try. The truck had received a DynoMax 3-inch system back in "08 after we experimented with installing a straight through muffler onto the stock piping. As mentioned, we had moderate droning with the muffler-only mod, but the full system is relatively drone free. It"s a little “dron-ish” cruising in the 55-60 mph range or when pulling hard at low rpms, such as a grade in overdrive. Not objectionable, but noticeable.
You can see the stats in the table, but there was no significant difference in 0-60 times between the existing DynoMax system, no system and with the DynoMax VT installed. Interestingly, there was almost no difference in backpressure in all three situations either, with the VT setup generating about 0.5 psi more than the other two. We tested up to 5250 rpm and the backpressure gauge showed about 5 psi in all situations — even with no system. That means most of the restriction is in the cats, an interesting discovery. We may install the stock system again just to see how much it adds. In any case, 5 psi at 5250 rpm is pretty good.
