Would I be able to take the Rinehart 2 into 1 exhaust off of my 2006 Wideglide which is an 88ci motor and install it on a 2007 Superglide that has a 96ci motor?
According to the Rinehart website the exhaust that I have says...

2006-Later Dyna 2-1 Chrome

$739.95

SKU: 200-0300


2006-Later Dyna 2-1 Chrome

NOTE: Customers with 2012+ models will need to purchase an O2 bung adapter kit, sold separately.

 

2006 and 2007 were the same transmission (brackets and oil filler location) and O2 sensor location. Should be no problem.

 

Should bolt right up.
I have a set of bannasi exhaust on my 05 super glide that came off my 2010 wide glide.
It fit perfect.

you should have no problem it fitting.
