Installed my AT2525's last week, love the sound associated with them, however, I want just a little more rumbled at idle and low rpm driving. Would the next step up be a high flow cat? H-pipe? I can't start gutting cats unfortuneatly because my car will be going back to Mass (where everything is illegal) and I'm currently on a military base (where the max speed limit is 35mph:sleepy:) I'm just looking for the next step up with moderation..Thanks again.

Do you have res-delete tips or factory tips? Are you going to be driving to Mass? If so you should make a little stop off in Maryland and go to Mandrel Bending Solutions and have malibuguy "Greg" install some over-axle 2.5" mandrel bent pipes for you. That will increase sound, as well decrease some interior cabin drone and he can also extend your tips out slight which also helps cut down on some interior cabin noise.

I have the factory tips, the only exhaust work I have done is the AT's. I really like the sound of yours in your youtube vids. What is the mandrel bent pipe solution? Does bending your pipes over your axle have something to do with the sound?

Remove your second set of cats and you will hear a noticeable difference!

And you shouldn't have a problem with emissions.
