I've never tried it but I doubt it. The cylinders are taller meaning there'll be a wider spread between the exhaust ports.
If the pipes are split an extension could be added where the two pipes join and a heat shield would cover the extension.
Installed the Big Dog pipe on my FXR. Whadda ya know! It fits! Well that's news to Me. Guess ya learn something new every day. The guy I bought it from was having a hard time selling it cuz nobody knew if it would fit Harley engines. So I got it cheap. $90. Very cool. Here's a pic.
