I just bought an 03 Mazda MAZDA6S, 6CYL 5SPD and I am looking into putting some money into it. So, first things first: exhaust. I need advice on what kind of system or even tip to get. I want it to have a deeper more aggressive sound like a tuner. I don't know if I can get that with just a muffler tip? Does anyone have some advice on what to get and where I can get it? Second, I want to get an intake but not sure if I should get a cold air or short ram? Help me please!
