Updates:
1 - We are waiting to hear back from Wade about how the production run is progressing - it's scheduled to be done this week.
2 - This past weekend we fitted prototype headers to a 6 gen. We needed to trim 5/8" off the collector exit, then OEM 6 gen mufflers fit great. By early next week I will mount the now-trimmed prototype to my 5 gen to recheck fitment. I'll use an OEM muffler, TBR slipon, and Staintune slipon [Using both support brackets on the Staintune to lock down positioning] to confirm that proper fitment is maintained on 5 gens after the 5/8" trim.
3 - We have an 8 gen loaner in our sinister clutches. Monday Duc2V4 mounted new tires while I installed speed bleeders and new brake/clutch actuation fluid to get acquainted with the 8 gen - neither of us have one [Yet]. We will be installing a PCV on the 8 gen. One of the production run 5/6 gen headers will be converted to the 8 gen by modeling the curves of the 8 gen front primaries. Wade will build a prototype, then we'll do a baseline and dyno tune April 6.
