I'll toss another one at you that will give you "2 Exhausts in one". Look at the Innotech system its GREAT! With the valves closed its quieter than stock and with them open its loud as hell. Another plus is there isnt any drone that you would have if you went with gintani. There also are not any CEL light issues if you end up going with a full cat less system in the future.
