I'm contemplating to install headers and valvetronic catalyst / muffler for my Nissan Safari to improve its performance i.e. HP & torque.
In brief, will the headers and valvetronic catalyst / muffler hinder the car registration in Abu Dhabi and be considered as illegal
![Embarrassed :oops:](./images/smilies/icon_redface.gif)
If they are legal and will not stop the car registration, do you recommend a workshop in Abu Dhabi? I need the valvetronic to minimize the noise while driving in the city and on highways.
Apologies if there was a previous forum about the matter as I was not able to find anything about it.
Thanks!
