Magnaflow mufflers are awesome. They are a straight through pipe that's perforated in the muffler body packed with fiberglass and steel wool. No other muffler besides a straight pipe will give you less power loss. To get the sound quieter you will need to go with the largest bodies you can fit. Often times more than one.
These get louder after a few months once the wading has been burned in. I dont buy these to be louder. I buy them for better flow. I fit as big and or as many as I can to bring the sound level down. Generally one 24" body will idle close to stock. But if you open up the throttle it will be a lot louder than stock.
I hope this info is helpful.
The issue with all the magnaflow mufflers listed on Amazon is they are missing key info.
This is what you need to know.
This is a 5x8 oval body 24" muffler body 30 inches overall.
2 1/2 in and 2 1/2 out center.
