performance full system exhaust, how much its cost you bro.
that's awesome bro, well I think I like to put on my bike also, somehow get curious, should we need to retuned the ECU? and how bout the warranty, its the warranty void, for the major modification?
sorry bro..it's a really late reply..
it cost me around RM1000 for the full system and yes,we need to tune the ecu with a piggyback or standalone ecu..means, we can't tune the stock ecu itself and i recommend you to replace the stock air filter too..in my opinion for the beginning/first stage:
1. full system exhaust
2. performance air filter (K&N,DNA etc)
3. engine management (piggyback or standalone ecu)
4. sprocket (need consultation from the pros due to the weight of the rider and other matters that will affect the bike's performance)
I spoke with one of the kawasaki service centre staff, he told me that the warranty only void on the part that we had replaced only, means if you replaced the exhaust, the warranty will void anything that related to the exhaust only..but for the other parts of the bike,the warranty is still valid
it's my 2cents
