Tell you what, I hear this question asked every week. The reason why you're hearing so many different answers is because half of the people on here think that they're experts just because they've bought an exhaust before. What you need to do is speak to someone directly who specialises in your model of car. They are going to give you the best advice. Call/email Adrian from toda, ask him. He will give you the best advice. Not trying to be an ass, but you have to ask yourself how credible the advice is that you receive on forums. I know there are a few gurus on here, but there are plenty of people with no idea as well. Just bear that in mind.
