was wondering what flow master everyone is running on 5.0.40 or 50 series.

 

It is just a matter of personal preference. The 40 series is louder than the 50 series. Take your pick.

 

The muffler that you select for your F-150 will be based on your specific sound preferences. If you are trying to decide between a 40 or 50 Series Flowmaster muffler for your truck, there are a few things to keep in mind. If you prefer a more aggressive muffler, the 40 Series family will be the place to look. If you would like a deep, yet moderate Flowmaster sound, our 50 Series family of mufflers will better suit your tastes.

Flowmaster's 40 Series family of mufflers are a two-chambered design and include four of Flowmaster’s most popular mufflers. These mufflers will be fairly aggressive, and the tone will vary depending on which specific 40 Series you choose. We offer the Original 40, Super 44, Super 40 and 40 Series Delta Flow.

Flowmaster's 50 Series family of mufflers are a three-chambered design and feature a larger case, when compared to the 40 Series, as well as an internal resonance tuning chamber designed specifically to reduce drone. These mufflers are capable of producing mild to moderately aggressive levels of sound. We offer the 50 Series HD, 50 Series Delta Flow, Super 50 and 50 Series Big Block.

It is worth mentioning that Flowmaster produces over a dozen different series of mufflers, and depending on the sound that you are looking for, we have a muffler or a complete system to meet your needs. If you have any other questions or would like help finding a muffler or full system for your truck, shoot me a PM or give us a call at 707-544-4761.
