to add the Nismo exhaust to a coupe do you have to get a new mid pipe and muffler combination, or can you buy them seperately ?

How would it affect the sound to add only the nismo mid pipe w/ OEM muffler?
How would it affect the sound to add only the nismo muffler w/ OEM mid pipe?

how much are these parts ? dealer item ??

what has Nissan done differently to the midpipe and muffler to make the sound the same only louder ?

Is the OEM G coupe and OEM Z midpipe the same resonator ?
Is the OEM G coupe and OEM Z mufler the same other than length of the inlet pipe and length of the tips ?

thanks

 

is there a easier / cheaper way to make the OEM coupe exhaust sound the same only louder ? Like just adding some HFC's if so which ones ??

 

Yea you can add HFC's to make the stock exhaust louder, Fast Intentions and Crawford make good HFC's.
