What‘s the difference between Magnaflow and Flowmaster?Do they both increase the same amount of horsepower?Save the same amount of fuel?Which sounds better on a truck?I got a V8 4.7 quad cab, and can barely hear the engine running, and it feels like the truck‘s being robbed of its power.Which exhaust system will give my truck some confidence?
If your doing it for power or fuel efficiency, your doing it for the wrong reasons. An exhaust system is really only utilized when other performance parts are added like an ECU tune as well as a cold air intake or high performance heads. Also, most exhaust systems don't do much because no1 bothers to do exhaust headers, which are the most important part in my opinion. Your only as good as your weakest link. As for your question, the companies both make good quality stuff. Magnaflows seem to be a little quieter but have a very nice tuned sound. Flowmasters are a little louder (talking 40 series here) and a little more raw sounding. Either is an excellent choice. For trucks, i like the flowmaster 40 series. I hear good things about the 80 series as well. You can always Youtube the mufflers and i'm sure someone has taken a video of a truck like yours with those mufflers. It wont be great sound quality, but it might give you an idea. If your doing this, it'll be for sound, nothing more. If your expecting more power you are going to be really disappointeded.
