pipe help

[wanta450]

can anyone tell me if it is posible for my jetting to get richer by installing a big gun slip on and doing nothing else (everything stock) im trying to see if it will need jeted and how big i need to go :confused:

you will deffinately need to rejet to get the most benfit out of that new pipe, it will most likely be lean w/o rejetting

theres only one way wich it could get richer and that is if the pipe has a spark arrestor thats is not free flowing at all meaning that the stock pipe is flowing better wich I highly doubt.
