Hi, i'm from India. We got EFI version of 250R. I'm considering this GP1 exhaust system and have couple of questions:
1. Does installation of the exhaust system require EFI re-map?
2. I read that JUST replacing exhaust is nothing without a power commander, do I really need power commander along with exhaust?
3. Also, i'm confused between slip-on vs full system. Any idea which is ideal? With these mod, I'm looking forward to increase top-end power and growling sound.
I have never seen a 250R with this system on it, other than a couple short and crappy videos on Youtube. I am looking into purchasing this system but I would like to hear some more detail about it such as first hand sound quality and sound level.
A full system from Jardine for under $400 is awesome but I fear it is this cheap because it has no muffler and is just a straight pipe. Can anyone confirm this? Also, does it have cats? Any comments on power before vs. after jetting?
