Review on 🚗 Enhanced Performance with Flowmaster 43041 40 Series Muffler by Chris Hernandez

Revainrating 5 out of 5

Ford F 250 5.4L 2002

Came with some damage to the intake so I just warmed it up and got it back to normal. It only took 5 minutes. The muffler sounds great, not too loud but has a nice deep tone. I cut a knee off the exhaust pipe and threw it in front of the rear axle. If you want it to be really loud I'm sure this will help remove CAT. Sounds great on start, idle and start, once you get going you can barely hear it in the cockpit or outside. The muffler is not plug and play, you will need a 3" extension pipe and possibly a reset connector. tube where you need it. You can connect the exhaust pipe if you want, but I'm assuming you'll need an extension since the overall size of the muffler is only 19" and the stock is over 26". You will also need to attach the old hangers to the new muffler or just use galvanized braided steel wire to hang it. I recommend resetting it before the axis as I've had great results.

Pros
  • Trial for one year
Cons
  • Only available in white
