    Well took HRK suggestion and ordered the Fullsac exhaust cores for my SE 110 bike.

    I ordered the exhaust cores for midrange sound yet excellent performance. We have allot of farm animals around us and have to be real carful not to stampede the cows or sheep.

    As per the instructions I removed my end caps and then removed the mufflers. I also had to remove the muffler outer shield cover that comes with the stock exhaust do the SE bikes.

    After carefully with a die grinder and cutter I started grinding down the two welds on each side that hold the stock cores in place inside the outer muffler shell.

    Was a trick to get them loose at first but with the aid of a dead blow hammer and a round dowel I was able to remove the old cored.
    Once apart I discarded the old cores then took about 2/3 of the insulation and wrapped them around the new cores. I then took heavy wire and loosely wrapped it around the insulation. Enough to hold it in place but not to tight. The new replacement cores came with new screens to cover the fiberglass insulation and then pulled the ends up tight and used stainless wire to hold them together. Nice when you have all the tools and stuff so you don't have to go out and buy anything. I've re-wrapped older Harley muffler cores before when the fiberglass insulation needed new fiberglass insulation.

    Anyway it was an interesting project and one that does not take a lot of time to do. The exhaust does really sound good now, much better than the V&H 4 inch rounds I had on it before.
    Had to drill a 1/4 inch hole from the end on the bottom side of the pipe housing and once you install the new cores you place a provided 1/4 inch bolt with lock washer and nut on. Once done I mounted the pipes and cleaned them on the outside then picked up all the tools and cleaned the shop. Lots of metal fillings and fiberglass insulation in the shop.
    Here are a few pics of the project.

    I do HRK and thanks for the tip on them. They sound just right, not to loud yet not to soft. I can feel a definite difference in the power.

    Yeah it's a great deal

    If you decide to do your header they have a nice stepped header
    That fits under the stock covers or a swap program where the take the cat out
    Of a stock header and do a swap

    I run HD SEII (that's II ) on my 05 Fatboy 95 cu in. They are loud. Stamped by HD for "off road only". Between them, the SE air filter and FuelMoto PC the bike is fast and torquey. But, I am getting up there in years and whenever I do a long run I get tired of the noise. I have put the stock slip-ons a few times but I always go back for 2 reasons: the noticeable performance gain and respect by cages. There's no denying the fact I get more respect and room making noise. Maybe ear plugs is the answers?!?!

    You want loud Fatboy I have a set of V&H fishtails on my Heritage Softail Springer and they are very loud. I don't like them anymore and if I still had stock mufflers for them I would put them back on. They give you a lot of torque and yes the power increase is amazing but just to loud. When I fire it up everyone takes notice.

    I know, a riding buddy has em on his soft tail. They are louder than mine and make a god aweful brapppping type sound. I don't want loud, Id like to get half way between my SEII's and stock but I can't afford a whole set of pipes and mufflers. Harley changed the pipes in later models removing the crossover from the mufflers and putting it in the pipes. Hence, i can't get slip-ons anymore.
