I need to be 96-97 dbs, so loud pipes such as Rossier or Sparks won't be my choice. Also, I don't like K&N type filters, especialy without airbox. I'd like to know how to modify my airbox and still protect air filter. It's MX purpose bike and I like to have good low end.

Get a venom Pipe, they make great power and have low DB i believe 97. This will prob net you a few hp.
