I'm assuming when you say "custom" you just mean aftermarket. If you've modified the Remus exhaust in some way no one is going to have a map for you. But any 2 into 1 exhaust with your mods should get you close.My searching here has turned up no one conversing about this particular exhaust system and tuning for it specifically. But possibly someone will chime in with some helpful information.
