I'm thinking about removing the baffle element from my Cat Converter.

I have seen a little deflector shield put in to divert some of the exhaust gases down the left exhaust pipe, is this divertor needed.

What gains will I get from the removal of the baffle element from the Cat, do I have to do a re-map or can I get away without doing it.

At the moment the bike only has Fishtail slip on's (absolutely love these) and the restrictor plate taken out of the Air Cleaner.

Would I get any benefit from partially removing the Baffle material from the Cat Converter, I believe it's only a aluminium material

Hey Steve, if you rev your engine out to higher rpm, you will get a bit more power BUT you will need an Indian High Flow (Round) Air Cleaner first to let more air in to the engine.  However, others have reported losing a bit of lower rpm torque.

I have kept my cat as I shift up by 3,500 rpm so this is not my first hand experience speaking.

Also your exhaust will sound louder too.  If that is what you are after...

What do you want to achieve?  More power or louder exhaust sound?

I'm actually trying to reduce the heat from the motor/exhaust but a it louder pipe noise would be nice as well. So removing the air cleaner restriction would make no difference.

If reducing right thigh heat issue, I understand the removal of cat will do nicely.  Another option is Power Vision CX tuner.  But if you want louder pipes, removing cat sounds like a viable option for you.

Removing air intake restrictions do help improve the performance of your bike HOWEVER, I don’t believe you will ‘feel’ the performance improvement by removing the cat without better flowing AC and even then, only when you are really revving the engine.

Oh, by the way.  The factory stock tune can cope with fitting a stage 1 pipes OR high flow AC BUT not both... meaning, you have already improved the air flowing in to the engine with modified stock AC... I am not sure if your tune can cope with better exhaust flow and less back pressure as well.  So, maybe you might need a PVCX or suitable Indian tune... say, the one that comes with Stage 1 & AC or something like that (this is just a guess, not sure if that tune will work 100%).

I fitted a Fuel Moto Jackpot header, more expensive than gutting the cat but did not want an expansion chamber in my header. Has a great effect on the heat much cooler. Also have a Wimmer high flow filter, 60mm throttle body, PCV and dyno tuned so this also helps

Before you Rip out the cat, you will need to buy a dynojet tuning device and download the software so you can re-flash the ECM, book dyno time or your wasting your time, but when you do you will get 20% torque.
