Its no problem.

If your BF has a cone and he knows how to intsall one, I would go that route because it does add some pretty cool sounds. :P :D and its cheaper.

For simplicity, I'd go with a simple drop-in filter but you wont notice it as much as a cone. Some here will say the cone adss 'XX' amount of horsepower, from my experience it adds noise, and may smooth out the power band a little...thats about it.

It is really up to you, the drop-in filter is usually about $20-$30 more than the cone.
