N14 JCW vs N14 MCS exhaust question

This forum is a great source of information but I've yet to find what I'm looking for, maybe a kind soul can answer this simple question. What's the difference between the two exhausts? Are they identical up until the muffler? TIA

R5x S & JCW Exhausts are different

Based on my 2009 S and my 2009 JCW.

The S has a second catalytic converter and the JCW doesn't. I believe the mufflers are different, and the tips are different.

I have really enjoyed the JCW exhaust...the S was good, but the JCW is a touch louder....and the pop & burble of the JCW is great...my S didn't have it.

I remember somebody said because the JCW engine has bigger valves and turbo, the entire exhaust has a larger diameter.
