this is me with most cars...
i'm not completely retarded, but i'm not smart.

can someone help me wiht my exhaust. my muffler's fallin off and tail pipe is smashed in several places on my 1970 buick lesabre. my friend wanted me to check this out so i'm not so clueless. can anyone explain to me what parts i need for my 350 engine. i just want decent exhaust (pipes, new muffler, headers?) so my gas mileage isn't terrible and so it sounds like something worthy of gasoline. please explain it in english so i don't get frustrated and take it downtown.
