TTI Exhaust has one piece 1 5/8"- 1 3/4" stepped headers w/3" collectors. Options include coatings, in and/or out. Plenty of ground clearance, no need for a 90* oil filter adapter and installation & fit is pretty good. If there are plans for merged collectors, you can always cut the old ones off & add the custom versions.
Specific applications are in the yellow shaded areas but B, E, F, and M are all the same. Possibly J as well.
