i got some info today from a muffler shop. He had a look at my car and said its easily done. Just get a muffler and they will weld a pipe to it that will bolt to the flange back. This will allow me to remove my stock and put this set up on or vice versa. Had a look around and decided to go with Remus but will cost a fair bit, $850 just for the muffler. Just wondering if anyone out there has this brand installed.
