So it clearly states that part #14394 will not work with your HD. I guess you missed that part, unless it wasn't posted when you bought your part. That doesn't seem like the kind of mistake Corsa would make though.
My purchase was made well before they updated their website. I specifically pointed this out to the representative from Corsa that #14394 does not fit my truck. He stated to me that "you have the right one", and was prepared to send me the correct intermediate pipe. However, I returned the item to the retailer and took a chance and order the model for the Raptor(14387). Guess what? It worked on my Harley, despite no reference to this on Corsa's website. Though, before I returned the original system I kept it until the new one arrived. I compared all components side-by-side, by part number, and measured each as well. The only difference between 14394 and 14387 (Raptor) was the intermediate pipe with a 3-inch diameter on both ends. I had my dealer install the Raptor version, and the rest is history. As of June 27 there was no update to this on Corsa's website ( I attempted to install 14394 on June 25). I periodically checked for a change on their website and I did not see any update until early August. So, my guess is that they updated their website in late July/early August. Though, many weeks after I brought this to their attention. I even captured a shot of the webpage for 14394 on June 25, and on July 6 for 14387 and have them in pdf format. Neither mentioned any compatibility or non-compatibility with the Harley, just 6.2 or Raptor.
On another thread within this forum I commented on the sound of this catback system.
