Okay, what's the BMW line for installing Remus exhaust on the KS? Will it void the warranty or not? My dealer has me confused...
But in the case of the Remus, the larger primary pipes are well chosen. Top end is better, but midrange is MONSTER.HGP3 said:Exhaust pipe or header size is determined by a lot of factors, some of which are power curve,lenth , fit and a lot more. Just making them bigger doesn't mean they will give better performance. Large usually only adds to top end power and may even hurt mid range power. Large pipes are good for draining dams and rain gutters but not always exhaust.
I've been doing a little digging on the aFE filters and the filtration levels, air flow and lack of filter oil deposited on air flow sensors that can happen on other pleated gauze filters makes aFE sound a good choice. Have you been able to use a standard aFE filter to suit the original air box ? It sounds like you are expecting the exhaust and filter mods to exceed the ECU's operation range - custom chip?rubbert said:I am waiting on the AFE filters and additional information about fueling modifications before taking her to the dyno in Tulsa. Filters should be here in 2-3 weeks. Hopefully the ECU debate and possible means to an end will solidify allowing a tune at that point.
