Doug,
The GT does not use equal length header. It does have a very nice boxer sound. The AVO exhaust is great! Not too loud, just enough to hear the deep boxer note. We have the computer, intake and catback on now. Dyno time is not until Fri. Then we will do the uppipe and downpipe and do a Stage3 map. It is alot of fun to drive. It's really fast now. Stage3 should be wicked.
