no there are 2 versions, one for off-road and one for on-road.
you can try a variety of pipes. a great combo is the Novarossi EFRA 2052 with a 6 fin medium header
you can try the new Sirio .21 pipe. forgot the part#
you can also try the Novarossi EFRA 2015 with a 6 fin medium header as well.
i like the first combo the best. but those are some choices for you.
