Does this pipe just give you more power and better powerband or does it increase speed also.If it doesnt Plz tell me a pipe that increases both power and speed i have a 03 300ex

Ity won't get you past the rev limiter, but it will get you there quicker. What your 300 really needs is a bigger header!! If you buy a new PowerCore, I think it comes with one. Mine did.

When I bought the PowerCore, it came with a header. It wasn't the PowerBomb, just bigger that stock. That and a K&N, made a very big difference in the little 300 engine.
