Mellow Sound for 2014 Toyota Tacoma V6.
The '14 V6 Tacoma comes with an offset to offset muffler. The Dynomax Turbo is not available in that design. I bought the offset to center model. Since it is reversible, I figured the muffler shop would be able to install it. They did have to add one section of pipe to make everything fit and install new hangers. The muffler cost about $70 and the install was $125. I was hoping he'd charge only $100. Nevertheless, that was still a lot lower than the $250 estimate had I bought the Magnaflow muffler from the muffler installer. The Dynomax Turbo is just a little louder than factory; the exhaust sound at road-speed is pleasant. It is not the "ratty" sound you hear from single or dual exhaust V6's. I will add that my old '94 V6 4.0 liter Ford Ranger sounds a heck of a lot better with just the factory exhaust. I suppose that has something to do with OHV engines compared to OHC. OHV delivers more "lope" sound. However, after 22 years in the Ranger, it was time for something new. Besides, the 156 hp of the ranger does not compare to the 236 hp of the Tacoma. Same size engine, but 22 years of tech change equals more right-foot excitement.

Dyno Muffler
Great muffler. I had to do some welding and modification to the tail pipe in order to fit (expanding the ends and cutting of the tail pipe), but once attached it seems to work great.

Great Product
The muffler fit perfectly to my original pipes. Once connected it made my v6 sound like a V8. Also the h.p. was added and it saves gasoline.
