Magnaflow Muffler

Magnaflow Muffler and Exhaust

First, I must say that I believed the mechanic installed a Flowmaster exhaust tubing system on my car with a Magnaflow Muffler, but when I originally wrote up this article, I figured it was all Flowmaster.

My 2 and 1/2 inch Flowmaster exhaust is simply a dream in comparison to the 3/4 inch smaller tubes, which were most utterly not a Flowmaster exhaust and Magnaflow muffler in any shape or form. The torque boost that Auto Bravado's car received in gears one through three was incredible. In other words, my acceleration was much better at lower speeds. Having a larger Magnaflow muffler and exhaust should make a small boost in your power on the freeway, but it'll effect your efficiency even more than in the city. My freeway mileage increased from 46 under the best conditions to 56, even if the on board power didn't seem to increase that much. These results were obtained with a 99 Chevy Prizm, any gains you receive on your car or truck will be individual from your Magnaflow muffler and exhaust especially considering that my Chevrolet has had many other modifications for efficiency, which create power. The base line of where you get more power should be about the same regardless of the vehicle's designs. You'll get more torque or acceleration increases out of the lower speeds if you upgrade to a larger exhaust, and an efficiency increase on the freeway.

Can your exhaust tubing and muffler be too big?

Be warned, if you go too much larger with your Magnaflow muffler and exhaust you will actually get a decrease in your mileage. My friend and mentor put a 3 1/2 inch exhaust on his old Dodge truck - a nice boost from the 3 inch it came with, but he also went for dual exhaust from each side of the V engine. That was just a little too much Flowmaster exhaust for the design of that engine! He had to keep his engine at 2000 RPM's just so it wouldn't die. He had unbelievable power, and a lot of fun for a while, but it had made the truck barely drivable. He went back to bringing the Flowmaster exhaust together with one Magnaflow muffler, leaving the 3 and 1/2 inches of tubing and he had the desired effect: more power, and more efficiency, without a down side.

Magnaflow Exhaust

The first trick to understanding your Magnaflow exhaust tubing is that you’ll want to go larger to get more performance and better efficiency, however, you can go excessively larger, which will actually reduce your power and efficiency.

Magnaflow exhaust tubing size recommendations:

If you’re current tubing is 2 and ½ inches I recommend upgrading to Magnaflow exhausts tubing of up to 3 inches. If you are starting with upgrading a car rather than a truck, you’ll probably have anything from 1 and ¾ inches to something a little smaller or bigger. There are so many foreign vehicles, that it useless to predict the exact size. Here is the general advice: go between ¼ inch to ½ larger than your original size and you should experience a richer sound, more power, especially at slower speeds, and usually better efficiency.

Warnings about overdoing the size of your Magnaflow exhaust tubing upgrade:

Magnaflow exhaust, if not done to an extreme, will generally improve the efficiency causing your truck or car miles per gallon to be increased. Generally improved fuel mileage, is all you can ask for because if you use your Magnaflow exhaust upgrade to have a lot of fun and accelerate quickly, you can actually achieve poorer mileage than you ever could have before you upgraded your tubing to a Magnaflow exhaust!

The richer yet louder sound to be expected:

When upgrading to larger exhaust tubing, whether you go with Magnaflow, or other trusted brands available through links provided on this page, you need to be prepared for the louder sound. Some of you will be feeling excited about this, while other’s will be thinking about whether this’ll be worth it. First off, when ever you have new Magnaflow exhaust tubing or larger tubing by any other brand, it’ll start louder when it is first installed, and as time goes on that sound will reduce as carbon from your engine coats that resonating metal into something quieter. Secondly, the gain in efficiency, in this day in age of expensive gasoline, is worth a little noise.

In conclusion:

In conclusion, your engine will last longer and you’ll spend less in gas. Yes, it’ll be louder, but the gains in Auto Bravado’s mind and many of your minds, will conclude that a larger Magnaflow exhaust tubing, which should be and accompanied by a high flow muffler, whether it is by Magnaflow, or the good folk at Flowmaster and their incredible exhaust’s sound deadening technology, the gains/pros will overturn the losses. The cons of this upgrade being losing a quiet running car (a gain to many of you), which in time quiets up a bit, an inefficient and slower running vehicle, along with inferior performance, and excessive use of gasoline.
