I have a jdm motor with greddy td04. I realize that the down pipe from the turbo will not bolt on to my exhuast. I was told I could use an exuast from an na. what i would like to know is does anyone know if i could use a different down pipe so i can use my tt exhuast????

 

I woul dnot get a diferent down pipe. but instead get N/A test pipes and from there on I think you should be fine with the TT catback.
