Doing headers/exhaust is not a problem if you're handy with a wrench. Only thing I would suggest getting if you don't have it is an Oxygen sensor socket a cheap torque wrench for tightening the headers and the repair manual for your year car. The exhaust might be hard if you can't the the car high enough to work under it. But if you have the cash, a decent exhaust shop wouldn't charge you more than 50 bones to bolt it on. Oh and rusted bolts come off easy if you spray them with PB Blaster spray and let em sit for a while
