FMF RCT 4.1 Titanium Full System Exhaust fitted on a 2018 Husqvarna FS450 supermoto with dealer FMF map installed on bike.
About 70-80% the weight of the stock system in total (smaller difference when comparing mufflers, larger difference when comparing header pipe weights).
Massive increase in sound
Excellent fuelling/throttle response from the dealer map (as good as stock or better at all rpm/throttle openings)
Very noticeable increase in power. By my estimate about 4-5hp, mostly in the first half of the RPM range, especially low down.
No spark arrestor or DB killer used
