Just got my new head pipes from Vance n Hines, do i need a fuel controler with the head pipes?
Thanks

 

To get the full benefit out of your new headpipes (i.e. the catalytic converter is now gone), a fuel controller is needed. Most folks replace the headpipe, add a fuel controller, and get an air cleaner/filter that allows more air flow. AKA a stage one. Some replace the mufflers too. You can certainly add these in pieces one at a time if funds are in short supply.

 

+1 on what Sageone said. But, remember that if you don't do it all at once, every time you make one of those changes you will need to have your fuel management device (Fuel Pak, PCV, whatever) remaped to make sure your fuel air ratio stays where it should. (meaning your not running lean!)

 

Already have the mufflers, and that took the cat away. I was under the impression that you only need the fuel pack with more air intake? I already have the fuel pack so it's not that big of a deal, it's not on the bike yet.
Whats a good way to mount the fuel pack, i do not have the mounting parts, just the fuel pack itself.

 

Pipes + better AC + fuel controller = $$$$$ and stock pipes for me. That is until I win the lottery.

 

Well i got lucky bought the slip on's for $200 like brand new lastyear and i was given the fuel pack for nothing and i just bought the head pipes because i want a better sound and hated the crossover on the stock pipes. The air cleaner might have to wait.

 

Never tried it without changing the A/C, but you may be able to get away with not installing the controller. Higher flow through the system is what prompts the need for a change in fuel system management. Since you still have the restrictive factory A/C on the bike, you may not see enough change in flow to warrant the controller. One way to find out is to fire it up and see.
