You can do exhaust but it has to be CMI becaues it will not void your warranty becaues that system is used on Mercury Racing Product. The filter is no problem either. Remapping the ECM after the exhaust and filter install is a good idea. Then you need to get all that power to the water with a lab finished prop. We can provide all these things to you contact me 1-800-376-1616 Ext 208 :cool:
