I want to add more Power to my 300ex, So I was going to add a K&N Power Kit to it to increase the horsepower, can I put the kit on without any other modifications? I don't want to spend alot of money. Would you suggest to just buy a White Bro's pipe instead of the kit? I don't really want to spend $250 but I might be able to manage. How much will the power kit help? Please help me!!!
