It will cost more no doubt. You will also need a tune but let's be honest, once you start modding you will keep doing it. If you can swing it I'd do downpipes, dual intake, & a tune. It will be a different car. I'm running megan dp & test pipes right now. I know many here don't like them but they've treated me well & they were $250. They will outflow your pre cats by a ton.
