you must not have a true hmf header. HMF header is alot longer and connects to the muffler without a mid pipe.

this is a hmf header

its a true hmf header it was a full hmf exhaust the slip on just fell apart and i have just the header left i was thinkin about trading for different slip on the guy has a stock header on his thats why i asked the question.....im not talking the length of the header im asking about the diameter of where the muffler slips on on the header are they the same?

stock head pipe is bigger around than hmf header. its designed for more low-mid i would say. i once traded a buddy my stock header and mid pipe for his hmf header. i couldnt tell the difference honestly

in order to make a slipon a full system all you do is ditch the mid pipe.

in order to make a full system a slipon you need a stock header and mid pipe. (cannot use hmf muffler on stock header without midpipe)

hope that helps.
