so i noticed from day one that my exhaust was loud. this past weekend i checked and applied some exhaust hole filler. it didnt fix it. so i looked again, i have a pretty large hole in the down pipe where the two hagers are welded on. ive emailed kfx to find out if they can do anything and they have yet to respond. i think its fair to say that since its been installed for less then 1500km they should maybe send me a new one. what do you guys think?
