I have just purchased a 2008 Rocker C from the states attached to it is a set of Vance and Hines big radius exhaust from what I can see without currently having the bike in my possession that is all they have done to the bike and it has no air filter change done or any other mods in regards to the performance to match the exhaust. Any advice on extra requirements would be great. I get the bike early next week so I need about that long to convince the bride that I am spending more cash on the bike before I get it.

Where in the great brown land are you located ?

If you're in Perth or close-ish I can maybe help

i am in Melbourne

Remember the Rocker stock exhaust is an "orphan" in that only the Rocker models use that system

A Heritage /Custom / Nightrain / Softail standard system WILL NOT FIT !!

Fatboy / Deuce system different again, they don't fit Rockers either

Dyna systems are not even close !

If you're buying a bike stateside then try real hard to get the stock system from the seller if you can

Easier with a private seller of course.

And yes mate you'll need a stock system for "compliance" and state rego in any state.

And sorry the tyranny of distance means I can't help physically mate.

i have the stock exhaust for it and the bike has the stock filter still in the bike, i have the bike but it is just finishing off the compliance part of the buy.

so from what i can tell when i went and had a look today was that it has the big radius pipes for it but no other mods been made to the bike. so i am after a ballpark guesstimate for the parts i will need to conplete the bike.

thanks everyone for all your help have decided to go for the dynoject powervision with the screaming eagle heavy breather.
