Recently installed a Muzzy pro on my 05 brute 750 and have not had good results. every connection leaked including the headers right back to the connection to the can and even the can leaked from the back where the bolts go around the can. no matter what way i tried it every angle every thing i could think of it still leaked everywhere and the front headpipe touches the frame and the pipe that runs along the left leg are from the front header no matter what i try always touches the side of the valve cover causing it to melt. my question is will i have this same problem with a HMF full system. Are they the same design as Muzzy what are the connections like? Ive pretty much had it with this Muzzy and will be sending it back. hopefully getting my money back.
