Well it wasn't my car or today... but yesterday i was at the drag strip with my brother in law. He was running my nieces car and his dad's 69 camaro. It was a good time! There was an ek and an eg giving it hell out there, but i think both were testing. There was also a corolla coupe of the ae85/ae86 variety out there. He had a parachute on the back but seemed to be working through some tuning issues, car was slow...

Got oem front left & right drive shafts installed. Front right was shot to hell and left was pretty bad. Took care of the violent shaking under acceleration!! So damn happy lol

So, thinking of doing an exhaust swap on my Civic. Nothing special, just a catback at minimal costs. A guy local to me has 2015 Si Sedan with an Invidia catback that he is looking to trade for a stock exhaust. I looked up the part numbers and the 2012/2013 exhausts are different than the 2014/2015 version (and, wikipedia says Honda retuned the exhaust for those model years getting a slight boost in performance).

12/13:
Cat to muffler: 18220-TR7-A01 or 18220-TS9-A01
Muffler: 18307-TR7-A02

14/15:
Cat to muffler: 18220-TR7-A02
Muffler: 18307-TR7-A21

However, I wasn't able to find much information on what is different about the 3 versions; but, from what I could see online, most aftermarket exhausts are 12-15 which leads me to believe they are interchangeable. Thoughts?

You can interchange. The muffler and b pipe changed slightly in 2014, which made the part numbers (and 4hp) change.
