Flowmaster Super 40 Series Muffler Review
There are a lot of that are thinking of purchasing an aftermarket muffler for their car or truck. There is a large amount to pick out from out there, all with their exclusive added benefits and seem. I purchased the Flowmaster Tremendous 40 Collection Muffler. Flowmaster statements it to be a single of their loudest, higher flow mufflers. In accordance to Flowmastermufflers.com “The Super 40 has that “deep strong” audio of the unique 40 collection but with all the advantages of general performance and small inside resonance from the “Delta Circulation technology.” I have to say that I agree with the point that it has a deep potent seem, having said that, the interior resonance is major. I have not heard the interior resonance of a delta circulation, but the Super 40 Series even now has really a bit of inside resonance.
I set this muffler on a 2001 Toyota Tundra 4.7 Liter V8. I purchased the muffler on-line, and when it arrived I took it and the truck to a area muffler store and experienced it mounted. The store simply just reduce out the stock muffler and mounted the new a single. The resonator was remaining alone. I also added a stainless steel idea. From working day 1, I have been quite amazed with the sound of it.
Involving.5 & 2 RPM’s the seem is quite throaty and deep, in particular when I an actually on it, even so as my RPM’s raise higher than 2.5, the sound from the cab get a minor quieter and the rev of the engine can take about the sound from the tail pipe. It continue to sounds really terrific in my opinion, it truly is just not fairly what I expected.
As considerably as general performance is concerned, I experience that I have dropped a minimal reduced conclude power. With higher move mufflers like this a person, this can be frequent. The horsepower gains that are claimed are correct, nonetheless, the amplified horsepower is found at the larger RPMs. The loss in minimal end electricity is plenty of for me to discover, but not ample to make significantly of a change. (I’m picky)
I have not recognized an enhance in MPGs. I was hoping that I would, but it remained unchanged. (even with a K&N fall in air filter). I keep on to get in between 16 and 18 MPG.
Pros:
* Deep throaty audio in the cab and out.
* Good value.
* Amplified ability (significant RPMs).
Downsides:
* Not a stainless steel development, in its place it is painted. Following a number of months of use, the pretty black paint has pretty much all burnt off.
* Around 65 – 70 mph, there is interior resonance that I just will not like. It goes absent at about 72 mph, so not a massive offer. I preferred it at 1st, but will get troublesome after a although.
Overall, the Flowmaster Tremendous 40 is a excellent item. I seriously like the sound of this muffler. It is deep, and sleek. It is really not raspy and “rackety”. It generates a impressive seem and definitely lets you listen to the beast that the 4.7 Liter i-pressure is. It is one of the greatest Toyota aftermarket elements I have bought.
