Staintune Two Brother high mount There are many other less expensive but you ask for recommendation so the top two are the common one.
they do not make a high mount any more for the 5th gen. i have a two brother carbon can for a 5th gen. brand new never installed. it you wanted high mount all you would need to do is have the mid pipe made. if you want to keep it where it is you cut old mid pipe and use it with new can.
