looking at getting a tw bro exhaust for my 06 1000. all ive seen is slip on, geiss they don't make headers. if later on I wanted to put header on would the tw bro mount up. or would i have to but canister and all to fit. just wanting to save time down the road if i wanted a full system

 

If you want to go that route then go Jardine. Jardine has headers that mount right up to their slip ons without the hassle of buying a whole new system. Plus they sound great too.
