06 GT stock exhaust on 06 V6

Hey guys, I'm working with an 06 standard V6. A friend of mine Just replaced his stock exhaust on his 06 GT with some aftermarket ones so my question is; would it be possible to take the exhaust system from a GT and make it work on my V6? I have everything from the catalytic converters back, is it possible to just take out my Y pipe and install the stock exhaust from this GT? I just thought that if the converters were in the same spot it should be possible. I appreciate any help, cheers.
