rite now i have maggie highflows to a 40 series si/do. i want more noise though, i was gunna get the super 44 for a little more sound and flow but then i found this from jegs

looks like a single chamber muffler but i wanted a little feedback first, worried about the tone

 

correct it is a single chamber. IMCO was bought by Cherry Bomb and with it Cherry Bomb took over all the IMCO mufflers so the IMCO extreme is now the Cherry Bomb extreme. I love mine, great aggressive deep sound. Go with the 3"si 2.5"do and you won't have the popping that the first video has
