You are probably OK then but I would still dyno to be sure. They are lean from the factory so you may want to dyno it and adjust accordingly. Chances are you are not so lean you will hurt anything. Alot depends on how restrictive or nonrestrictive those pipes are. I never messed with those so I can't be sure. Maybe someone with experience with that particular exhaust can give you a better idea.

Dinquas calculator says 131.5 main so if you are running stock jets you are lean. I guessed your altitude and left everything stock except you said snorkle removed and K&N filter.

I learned all I need to know about life by killing smart people and eating their brains.
