yes it actually increases horsepower and torque its not going to be a huge difference in power but it will increase it a little you will also get great sound out of my opinion flowmaster has the better sound but magnaflow is better in the performance category

How much horse power is added to by using a flowmaster muffler?

well you have to realize flowmaster mufflers are not straight through like magnaflows they have chambers. the super 44 is only a 2 chambered muffler so you willl get horse power but not as much as if you put a magnaflow. but flowmaster does sell a muffler called the outlaw series its just a straight through exhaust with no ceramic glass packing in it. so it will be louder and flow better than magnaflow. so your answer is if you want it loud but want max horse power go with the flowmaster outlaw series but if you just want a nice deep tone not to loud but still good flow than i would saw magnaflow

Can one drive a car without a muffler?

You can drive a car without a muffler, but you should not. It is illegal. Driving without a muffler allows many pollutants into the air. Technically yes, a car can be driven without a muffler but there are a few good reasons not to do so. The most important risk of not having a muffler is that there are laws regarding sound levels and a car without a muffler might be over government approved noise levels resulting in not being in compliance with the law and the end result being a fine. Another reason for not doing so is the impact it would have on your vehicle. A muffler on a car will increase its performance, efficiency and power output. It will also decrease the wear and tear on the engines’ parts.
