what will fit
#1
I have a 01 raptor when i bought it it already had a header and pipe. Well the pipe is no longer attached and i dont know what kind of headpipe it is. I was wondering if any slip on would work

Well it really depends on the diameter. If it's a stock sized pipe and ends in the stock location, then you have some choices. If it's an aftermarket header with a larger or smaller diameter, or a longer or shorter head pipe you are pretty limited, probably to the same canister that came off it.
What kind of canister was it.
