Flowmaster Cat-back Force II 1999-04 Mustang V6 or Magnaflow Cat-back 1999-04 Mustang V6,
the flowmaster only have 50.000 mile warranty, and the magnaflow have lifetime warranty.
so which do yall think will sound better.
Flowmaster is waaaaay louder... U can get pulled over 4 it...
I would go with a Magnaflow, your V6 will sound like V8 and it will pass the emissions... we used it on a Cobra+ couple more tricks and it was NASTY !!!
