I have been installing kits from ZoomBicycles for a bit now. I am on average happy with them
However their new kits have a black muffler that has a cat. converter in it....it totally robs the power, on some machines to the point that it will not go up an incline.
If I swap put the new muffler and replace it with an older style the kit is great.
Anyone have a fix for these restricting mufflers?
