Hard to put a cat-back exhaust on myself?

[C's 94 InTeGrA]

i think i do... but really.. i dont wana full with the whole thing. everytime i try to do somethin on my car i always fuck somethin up. i got quoted 35-40$ today from a shop here depending on how hard it is to put on. and i was like its a bolt on and hes like well they say that but it sometimes isnt the case... real jackass there. but anyhow.
