Hey, I just bought a 2008 Mustang GT Premium and it already has an after market exhaust on it. It's a JBA axle back. The cats are still on it. It sounds good but it's a little too quiet for my taste. I need something a little more aggressive. I've been thinking about buying Muffler Deletes but I don't want to make it too loud where it sounds bad. I've listened to countless youtube videos on different exhaust but you still really don't know how its going to sound in person. Should I keep the set up I have now and switch to an off road H pipe, or is there another exhaust that will give me some more sound and be more aggressive? Should I go with a Muffler Delete set up? I would really appreciate any help and input anybody can give. Thanks
