cheap as sob. exhaust ? . what would happen if punch plug out drill holes in bottom of air box to let more air in and add K & n filter. would this sound decent and not hurt performance? :bigsmiley10:
Do it the correct way or leave it stock. The K&N used in the stage 1 is taller for more flow so after chopping everything up at best you'll only be a bit better than you had.
Plus as Hobbit said, you'll need to do some fuel enrichment anyway.
I was told to do this by a local bike shop owner. My bike is carb and looking to make it a bit loader than stock and not hurt proformance. Thanks for the input.:33:
