I've searched around, didn't have much luck. I've got a 3/4 system already, so pretty much free flowing path for exhaust. However I still have stock headers which from what I read are great in the fact they already flow well and are titanium. When comparing header upgrades with a bike that already has a 3/4 system are there any real world gains to be had in the overall power hp/tq curve? Not necessarily peak, but a general increase across the board. Options out there range anywhere from that SS header they sell on ebay, to higher quality headers like graves SS or TI.
Is there a header for the 07/08 models that would offer an improvement to a bike that already has a 3/4 system? I guess one that would justify the expense.
Not sure anyone makes respectable headers for 3/4 system, no real gain from SS to Ti, if you want power you will want a full system, though your exup in the stock headers really help low down power so you may wish to keep it how it is.
