Can someone let me know if i can remove the resonator bymyself or i have to go a auto shop to get it done?

 

if u can cut and weld then do it yourself.

 

Been doing a lot of reading here ever since I became a member and I suggest you take it to the shop.
However, if you do have the right tools and equipment, I guess you can do it yourself.
But from reading other threads, it isn't that pricey to get it done.
