exhaust sound mc

[james fraser 111]

just wondering if anyone could help.
when iv been driving my m coupe hard the exhaust sounds much better (sounds more throaty pops n bangs abit) but i want it sounding like this all the time, is they some sort of valve that opens in the exhaust if so is thay away you can make it stay open all the time?

Z3M or Z4M?

Could it just be that the 'zorst is getting hotter under higher load?
