Just want to clarify a few things as I must admit I've never paid much attention to them before.
Must admit in my teen years me and my mates just used to put on straight through exhausts on from various sources, stuff some chicken wire to slightly deaden the noise in and then rejet the carbs. One of the mates worked in the local garage so getting a warrant of fitness was never an issue. My girlfriend (now wife) said she could hear me leave home 5 miles away when I rode over to see her. Obviously this approach would not be suitable for the Spyder
So after that ramble here's my questions:

So after that ramble here's my questions:
- Am I right in thinking that pre-2013 RS's have the CAT built into the exhaust while 2013 onwards have the CAT separate (roughly where the Y join is on a pre-2013)?
- Do all aftermarket exhausts have packing that needs to be replaced regularly?
- Why use packing when a system similar to the normal exhausts could be used?
- Isn't the packing toxic when you remove it with all the crap from the exhaust gases?
- Has anyone dyno'd the before and after when they have fitted a new exhaust on an RS (without making other mods)?
