This advise is for everyone. Wife mode or GF mode is resonated HFC and 18" resonated. If you don't care and have a "screw you" mentality, then go for the test pipes/LTH/non-resonated TP/HFC plus none resonated CF CBE. I am holding out as long as I can before I am forced to change my NR to 18" Res
.
At the end of the day, lots of combinations available for everyone. Wait time is worth it and makes for an exclusive company.
