There is only one Caldina in the UK (to my knowledge) so you are unlikely to get an answer here. You might like to try TOC Australia for a more informed answer

Stupid question but why do you want to change the exhaust? Sure it is quiet but it is tuned for the setup, if you start frigging with it who knows what your performance will do. For example there is a butterfly valve on one of the exhaust tail pipes, I can guess what it does but do not know. Now it has a very well engineered mechanism so it certainly aint for show.

It's not entirely stupid mate. The boy's just trying to...tune. Messing about ain't healthy but better airflow HAS been proven to benefit rides dunnit? And the Caldina GT-Four doesn't come with a fancy butterfly valve :-P

Anyway man, what u can do is purchase an aftermarket backbox, (like the HKS Hiper series) but ONLY if u wanna increase the diameter of ur exit piping. It'll be loud though, as de-catting comes with the territory. What I opted for instead was a direct, plug-n-play swap for a TRD spec backbox. Doesn't drone at speed, but grunts like a man! harumph.
