Question JB4 + DP
Hey ...
I have some questions about JB4 and Primary and Secondary catless downpipes . Jb4 questions: Q1- The Econo, Sport and Sport+ mode still available on the console or it's not anymore usefull ? Q2- is the JB4 Remove Top Speed limitation ? Downpipes questions: Q1- Are you still able to de-activate the sound flap with the M sound control button on the console ? It is comparable to the sound reduction with the stock downpipes or still make very loud bang. I keep my stock sport exhaust. Q2- Are you able to erase code with o2 sensor with the jb4 If you have some advice to give me, or experience with this setup, do not hesitate. thanks

eco, sport and sport+ will still be used the same way. not sure about the top speed limitation. you will still be able to control the exhaust flap after having both primary and secondary catless downpipes. with the jb4 you will be able to erase the code for the 02 sensor but it will come back.
