Gotcha, thanks for the clarification. Looks like i'll be having my resonators cut out thenWhere did you read about 3 modes? All the literature says 2 modes for each, with a little more on the modes in the recent supplemental manual (no differentiation between the R and non-R). Only difference I know of is the inline resonators before the mufflers (eliminated on the R)
according to fordparts.com....2 different part numbers. Not a real big deal two have 2 part numbers, but likely not a big deal for ford since im sure the welding jig can be shared.Good question, makes me wonder if they'd fab a whole new cat-back system just for the R, or just bolt the resonators in
