i believe the tunable would only make sense if further mods are done, ie, s/c, header, pistons, etc. the trd exhaust only, the non-tuner version is fine. you can always add-on the tuner version if you do decide to further mod or for fun. but you need a dyno to fine tune it for max hp. the std version has already been tuned. would be nice if there was more interest or if cpe supplied more suppliers, ie. many suppliers offer the injen system which helps lower unit costs.... but the injen system is only intake, has smaller diameter and does not include a re-tuned fuel map.
