hey guys i have a honda 300ex and i have the whitebrother e seris slip on and i wanted to get the rest of the pipe (HEADER) does the header give me more speed or horsepower. Beacuse it 100 bucks and i wanted to see if its worth it thankzzzzzzzz

 

well it mmight on the 300 cause the stock one is soo small id say get it it woill increase airflow and that means more power prorbably not much power but some mabye like 1hp gain or so mabye a little bit more

 

The stock one is pathetic. Get the header!
