I'm still in the process of deciding which exhaust I want. I've narrowed it down to 2, active autowerks or dinan. I've heard the dinan exhaust and it sounds very nice, although the $999 dollar price does not appeal to me, seems a little high,but if its worth it I don't mind paying that, but I've also heard that AA is very loud. How much louder is AA than dinan?,and also aren't there different stages ( like stage 2 or 3) is one more quiet than the other. As you can probably tell noise is a bit of a concern, I want it to deffinatly be louder than stock but not to loud to were it would get annoying, especialy on the highway, and around neighborhoods late at night. Thanks for any info, and I'm not in any rush to get it, it will be at least 3 weeks before I purchase one.
