Customer Review: (see review/s)
  • The part itself was at a great price. It matched right up to the pipe I previously bought. Nice and easy. I guess it had to come from Cally. So it took a while to get here. The other part was here in less that 2 days.

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.
