i took a wack or 2 at my suspected clogged cat with a hammer.... and a ton of crap fell out.... so i decided to gut them both... but every time i stuck the rod inside the one cat is see a white puff of smoke out the one side.... i guess it has a small leak under the heat sheild... this accounts for the buzzing noise.... is there anyway i can fix this with muffler cement or something because i cant weld... it just has to hold me over till i get a offroad H.... but anyways.... my exhaust set up is almost finished 2 bolts to go... pass side header doesent have studs... so i bolt it up from thebottom... the problem is the 2 holes are different sizes and all messed up.... i really should just throw a nut up top.... its getting to be a pain in the ass.... expect exhaust videos and pics by monday
