    Is this a D plate?

    I just bought a 02 GP1200R yesterday. I have read that the cats go bad pretty frequently. I took a picture of where I believe the D plate would be installed next to the motor. I was wondering if there is a way to look at this pic, and tell if the cat has been removed and a D plate installed? I thought the spacer between the two parts of the exhaust looked like a D plate.

    I think you will need to remove the stinger pipe and look into it to see if a dplate has been installed. Both the Dplate and catcon have the same look from the outside.

    Thats were it goes but you need to pull the pipe to look. It looks to be a gold color,like the cat con.

    Thanks guys. I have done some searching before posting, so I appreciate not flaming me. Is there a DIY thread on how to remove/replace the cat/con with the D plate? Also do you need to buy a new gasket when you do this or can you use a high temp RTV with the original gasket?

    I always suggest new gaskets,they are cheap and good insurance.They can be reused if in good condition and the coating is not coming off.Thin layer of water proof grease works well.

    I have searched and cant find instructions/DIY/tutorial write up on how to remove the cat/con. I want to tear into mine today and find out if mine has failed.

    Riva states you can reuse the origional and to spray both sides with "coppercoat". Also, a good quick way to see if the cat is still installed is if the exhaust sensor would still be connected to the control box. If a D-palte was installed a chip is used to fake the computer controller into thinking the sensor is within the correct parameters. The chip looks like a small black plug. Search around, I just did the conversion last week. My cat was in pefect condition, but why wait until it fails.

    Also, don't forget the waveater clips and couplers on the power valves. The intake grate is also dangerous and should be changed.
