I live in Ecuador and it is not illegal to remove cats here. This is good because mine are starting to get blocked.

If I remove the cats, is it a must to do a tune or will the computer auto adjust the air/fuel ratio?

If I do need some type of tuning device please tell me your recommendations. I am at sea level, drive in town only, do not care about HP but do care about dependability and ease of cranking and running smoothly.

The guys here can easily remove them and replace with a pipe.

Thanks so much for your help!!!!

George
