Getting ready to go to an exhaust shop. I am planning on having them install a pair of magnaflows where my stock mufflers are now. It will change the sound of the exhaust, even though it is still the stock pipe setup, correct? I don't want to waste $175 if it wont even change the sound... I am looking for louder, but I want deeper sound more than anything. Guess I am just looking to see how much louder it will be stock exhaust, just new mufflers.
