wah, all i remember is my car got smoother untill now , some of my fren tht drove my car before say my car got more power than last time when i got my car ?
anyway what u can do is , go to the ekzos shop take the converter out then bypass with/without the centre bullet box , then drive for a week or so then you see the diffrence ......
i suggest tht dont put any bullet first try and see first wether you like it or not .....
normally those ekxos man will say this .
'mesti letak satu bullet selepas potong cat converter sebab kereta auto "
some say the car feels no diffrence , some say very power after taking out , so i dicided to try it out lor
for me is car went smother , fc better ....thrn i trow away my cat already
good luck
