I used the Ram Air Restorations 3" oval x pipe (kit) and the 2.5" mufflers and tail pipes for clearence and to be slightly quieter. I used V band clamps from the collectors to the round conversion piece and it really looks good and fits tight. I am limited in room in the rear with a Helwig rear way bar and a Fays2 Watts link for the rear to get around. The tail pipes fit with the valance splitters I needed to cut them 3" shorter on install. Pretty impressed but a good day to get fabricated installed and fit in. The small cost for the V - band clamps will make it much easier if I need to remove a header or the X pipe asssembly in the future.
The key opinion is "WOULD I USE THIS AGAIN?" yes I would as it really fit and worked well.
