Usually an indy BMW mechanic will charge $50/hr.
If you were to DIY it you'd have to either lift the car entirely or at least get the front lift supports on jack stands.
It'd be a lot easier if you had someone helping you and the right tools.
True, headers alone wont do much for you, but then again, a performance exhaust will do NOTHING with stock headers.
The headers BMW slaps on at the factory are VERY restrictive. So if you plan to do headers first, definitely do an exhaust later on.
+1 on getting the Stett performance headers, they are made of stronger stainless steel and ceramic coated so they'll stay cooler than ebay headers.
