Magnaflow mufflers are 2 1/4 inch which matches my factory exhaust tips. Improved the tone and reduced the rasp on my 2013 audi s4 with catless headers. Sounds awesome, just not when mds kicks on.

This is not the same magnaflow item that came under this part number previously. This page currently lists this same part number but with an incorrect description of 2.

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.
