It will sound very good, probably more even aggressive and raspier then mine! You may want to run a center muffler, as the Eisenmann is one of the loudest systems out there and will make your car MUCH louder then it currently is.
Also, let me know if you'd be interested in one of our CSL "style" airboxes.
