So, the conversion is completed guys!
First, I changed/modified the downpipe.
The catalytic converter was removed from the OEM downpipe and replaced with a 300 cell one.
Before:
After:
At the same time, the OPF was removed/deleted
Looks original from outside:
OEM Cat & OPF was removed...
Oh, I thought to do the coding before..good to know.
Because if I delete the OPF, I'll driving in limp mode and have to go to the tuner afterwards
What's the max. speed in limp mode?
I'm planning an OPF delete and maybe a 200 Cell downpipe.
What do you think?
I will consider also the XHP transmission software.
Yes, it's definitely quite from factory... but not for much longer 😂
Does that mean I can't change the exhaust system without a CEL?
I assume the same for a catless downpipe.
Limp mode all time?
I'm planning to do a software update/tuning anyway.
