New Exhaust for 05 r1200rt

I'm considering replacing the exhaust on my 05 RT. Wondering if there are issues in replacing the pipes all the way using a new system that eliminates the CAT?

On my 09 there have been no issues with a Remus header and remus slip on (insert removed) plus UNI filter. I also put in a booster plug for slight fuel enrichment

Pro's : greatly increased throttle response, better 1st gear performance, it helps to reset your adaptives with a GS911 after install, bike drives much better around town you will be amazed by the change in responsiveness. The change is not about a few HP, it's all about the better engine responsiveness.

Con's) : yup it's louder, not obnoxiously loud but louder especially for a following bike, this is the trade off, also you will get some popping under no load deceleration, resetting the adaptives helps this greatly, but does not eliminate it.

My Rt came with full Remus pipes and Hexacone exhaust. The exhaust was too loud for me. I took off the Hexacone slip on,but kept the cat remus pipes and cat eliminator and added the stock exhaust. It was a good compromise. More responsive than stock but almost as quiet.

I also have the Remus exhaust + Hexacone Silencer. Eliminated the OEM setup altogether. Am VERY happy with the installation (super easy) and it looks and sounds great. The few extra HP is icing on the cake.
