Why Compare?

Flowmaster 40 and 50 series have been in consideration for quite a long time when choosing a suitable muffler for your car. Fifty are considerably milder than the 40s. But then again, we are looking for loud noise but not too loud. However, cruising and power are the main factors that differentiate these two exhaust systems.

Mild To Moderate Exhaust Tone

The two-compartment 50 series muffler has a range that provides tone consistently from mild to moderate. Unlike the 40 series, the 50 muffler is known for its milder exterior and reduced interior resonance due to less vibration.

On the other hand, the 40 series is rather aggressive. It has a powerful and truculent exhaust tone that marks your presence among the crowd on the road.

Decreased interior Resonance

The Flowmaster 50 series also works as sound deadeners. It secures a quitter inner ambiance by shoving out the noise in the outer world. Since the tone is still moderate, it doesn’t entirely interrupt the external balance but evaporates.

Similarly, the Flowmaster 40 too has a noticeable improvement in the reduction of interior resonance. It isn’t very pleasant outside while offering a lot quieter inside.

Ideal For Street Cars And Trucks

The 50 Flowmaster mufflers are 16 gauged 409s stainless steel and are MIG welded for optimized durability. Since it is stainless, it is very neutral to exterior moisture and goes a long way. The trucks and regular passenger cars are constantly in motion under low maintenance, 50s will be an excellent choice.

On the contrary, the aggressiveness of the 40 series allows them to cope with street and strip styles. The Flowmaster 40 mufflers are perfect for undiscovered rural places since they work great off-road.

Improved Mileage

Since 50 series are made out of the best raw steel, the ride with these is pretty smooth. Thus, the fuel combustion is reduced, resulting in improved horsepower. The low consumption and effortless mild exhaust eventually lead to better mileage.

40 series has no internal packing to the blowout. It is the most aggressive-sounding muffler in its class that is excellent for street racing and off-road applications.

Race Proven

On a brighter note, the Flowmaster 50 muffler series is limited to daily use. The dual chamber gives it a modern look that copes well with the race car vibes. It allows the outer appearance to be challenging, yet the sound is subtle enough not to draw inconvenience.

One of the most significant differences between the 40 and 50 series is that, while 50 are suitable for regular cars and trucks on the concrete road, the 40s are more of a rebel version which is a complete match for racing. Its head-turning thunder-like tone will surely make you look more challenging.

Vehicle Specific: 

Where 50s are vehicle specific, the oval-shaped 40 Flowmaster comes along with the quality of universal fit.

Limitations

Even though the Flowmaster 40 and 50 series are supposed to mimic the output of a sound deadener, reportedly, they are not quite good in that sector. The job of the mufflers is not only to emit exhaust noise but also to provide an overall service. Nevertheless, they seem to prove less adequate.

While many users find it up to their liking, on the contrary, many have opposed the recommendation of the 50s. “Delta flow seems to have more baffles and less resonating,” states some consumers.

 Which One Is The Loudest?

As you might have already guessed, the answer is “Flowmaster 40 series”. By a considerable margin, these series are known for their trademark loud, thunder-like noise that will surely make people turn their heads.

 Is Flowmaster Louder Than Glasspacks?

The Flowmaster is better right off the bat. Flowmaster, 40 series mufflers, provide the most profound and powerful grumble that almost sounds angry and threatening.

Our Observation

The 50 series Flowmaster is an excellent choice for those who want a mild exhaust tone that is still noticeable, while the 40 series is better for those who want a more aggressive sound. However, both mufflers are good at reducing interior resonance and improving mileage. It is important to note that the 40 series is more aggressive sounding and may not be suitable for regular street driving. Race cars and off-road vehicles will benefit the most from the 40 series Flowmaster.

Summary

Flowmaster 40s and 50s are different versions of these models under the same brand. They both have an average decent rating of 4.8 stars out of 5. With both of them addressing different affairs, they are indeed distinct, by all means, you can settle for one of them according to your need.
