Customer Review: (see review/s)
  • Muffler priced right said it was a direct fit. Not the case. I spent more on the installation then the cost of the muffler. Had to extent and add a bracket to hold it up. The least the could have do e is put a bracket on to fit the application or said it needed professional installation or not a direct fit

Customer Review: (see review/s)
  • My wifes 2003 Mustang GT had holes in the original factory mufflers so it was time for a replacement. Went with a pair of MagnaFlows first but she didnt like their sound level (too quiet). Replaced them with the FlowMaster Super 44s and now shes a happy camper. The have a beautiful exterior tone not too loud but very aggressive. The interior is very quiet though with almost no resonance. I prefer a little more noise inside but she doesnt. Best of both worlds. Had these installed at a local muffler shop for best results. Dont want any exhaust gas leaks.
