Porting or headpipe

[la400ex]

Im building a 416 and I still have the stock headpipe but the welds are grinded down. I was wondering what would be the best thing to do, get a powerbomb or have porting done. I can get both done for about the same amount. I was thinkin about goin ahead and getting the powerbomb. I can work a few days over the christmas holidays with my dad and make enough to buy the powerbomb. Im not gonna be able to afford a full system for a long time. Does this headpipe work well with the r-4? What about the fmf hi flo headpipe? what will benefit me more, porting or a new headpipe? Thanks, Anthony

I would port it now, since you have a slip on already, then save up a few bucks and sell your WB, and get a full system ;)

You cant run a marathon breathing through a straw. Invest in the header first. That way, youll be making the most of what you already have.
