I'm in the process of buying a 2001 4.6 regular cab F-150. I want an exhaust system that has a deep, loud rumble when it accelerates. I've seen Borla and Magnaflow mentioned in some threads I have been reading. I have a 40 series flowmaster on my current vehicle, a 4.0 L, V6 Jeep Grand Cherokee, and I'm not real happy with it. I wanted it to be louder. Any suggestions are greatly appreciated.

Thanks

 

Neither Borla or Magnaflow have loud systems. If you use a smaller muffler, it will increase the sound level from any company.
