77' and 78" have the same exhaust system?

[Bjoj2003]

I'm looking to replace the exhaust system on 1978 t140e because it's all rusted out. Saw a set of 77" exhaust in eBay and wonder if it's going to work? Please let me know. I appreciate all the help.

According to the J. R. Nelson book, "Bonnie, the development history of the Triumph Bonneville, second edition," the exhaust systems are the same.
I only know what I read so take that for what it's worth.

Yes, that's correct. They are the same.
