Looking to upgrade my exhaust for a bit more aggressive sound and and some increased performance. I dont want it to sound obnoxious and raspy. Looking for something simple and relatively cheap. I know i get what I pay for. But if its all the same beside a name (Borla v Magnagflow) I can bargain shop. If someone could educate me on how to get the sound im looking for without over doing it. Good brands to use and just tell me the difference each choice makes.
