Hi, I'm a new member. I have a 2008 Cadillac STS V6. I'm not an expert on after market modifications, and I was wondering if I put a magna flow or Gibson exhaust on my car, would it sound like a foreign sports car, or could I get it to sound like the sts V series with a magna flow or Gibson exhaust? I don't want to spend my money and it sounds like a Honda accord. Any answer would help. Thanks!
