You don't need to change for OBD1 just for the long tubes. I haven't changed to OBD1 and don't intend to do so, but I do have LT1-edit and can disable SES light for EGR, AIR...
I think people are changing for OBD1 mainly to allow use of big fuel injectors like more than #36.

where did you get lt1 edit?

I would get a mail order tune from pcmforless.com, no SES light, and the tune is perfect.
