People use the word 'same' in sentences like 'the same car' (where same is an adjective and will take adverbs) or 'I'd like the same!' (where same is a pronoun and will take adjectives).
The problem is that sometimes people use the word same as a pronoun (by putting adjectives in a contextfront of it) when they use it in front of a noun; whereanother noun. In front of another noun, though, it can only be an adjective and not a pronoun.
In its adjective form, it cannot take adjectives - only adverbs, like any adjective at that.
Examples (not the best ones, but I hope they make my point): 'The taxi you and I used on new year's eve was the exact same!' (pronoun) 'On new year's eve you and I used exactly the same taxi!' (adjective)
Conclusion: when used together with another noun, it's an adjective and must be garnished as such.
