Exactly. And they need to do it quick
It is an EXCEPTIONALLY difficult bike to build an exhaust for that doesn't end up killing power. Any "quick" design is going to be loud, and it might end up in the same location... but you will end up paying a power penalty probably in the 3hp realms. My BEST design ONLY lost 0.5hp and that was with the airbox mod and the PCv. The KTM engineers did a REALLY good job of getting that exhaust built as well as they did in the space they had. They got a LOT of extra length in the system by playing a number of tricks in the canister... which is also why it's as heavy as a boat anchor.
