Pictures? How can we possibly begin to guess whether the headpipe on your blaster is sotck or not without seeing it?

I can tell you, a "fat boy 2" silencer is not stock but someone could have stuck a non-stock silencer on the stock headpipe...

i cannot tell if its a stock pipe or not. looks to be in pretty rough shape. upload a video of it running. i can tell the differnece between a full system and a stock pipe and aftermarket silencer
 
Nope that is not a stock header. Look closely at the front side of the header pipe to see if there are any company logo's.
