There is a high-way drone that is incredibly annoying. For practical use, which involves driving on the freeway, the drone is unbearable.

Product has a nice sturdy solid feel to it and has amazing welding. Overall, totally satisfied.

V6 mustang sounds great, nice sound for a v6. The cars acceleration is what i expected. Gas mileage is a tad bit better highway and in the city.

Like a roar but not that annoyingly loud sound.

The flowmaster flowfx resonator is packed well and does a fantastic job of eliminating annoying raspy frequencies. Its a muffler and fits east to install with *. Added mine after the resonator.

K&n filtersberk hfcborla midpipe. L turbo (no cats) and the sound is great. The only issue i've had with these is the tubes are dimensionally the same on both ends. They are not obnoxious like some of the people out there running straight pipes.

It was defiantly shipped to another customer and returned. The part has a big dent in it.
