Hey guys hope you're doing great. Today l was installing a new slip on and dropped a nut into the exhaust pipe. Fortunately, l improvised a magnet to take it out. While on the process, l noticed the catalytic converter looks a bit dusty/dirty. Where l live the gas is crap, l think that contributes to build up carbon in the cat faster.
My bike is pretty new 4k miles so far, but recently I knew about a guy who resolved a power loss issue in his gsxr by removing a dirty cat. l should say that l have not experienced a noticeable loss of power yet.

Do you know if the cat can be cleaned instead of removed? Any specific products for this task? l'm not considering a full system just yet since the bike may not pass the emissions test in a few weeks.

I have no idea, but when I googled Cleaning Catalytic Converter with....... up came these "autofill" suggestions. vinegar, carb cleaner, soap and water, degreaser, lacquer thinner...... So it does look like there is a lot of info on the web.

If you haven't changed your jetting to be overly rich, I can't imagine the CC getting clogged. Maybe the somebody's CC gets clogged because of this...

Installs some type of Air Fuel Ratio reader to log engines actual AFR results. The CC causes the AFR to be leaner than actual results causing the tuning software to created an overly Rich mixture? This then clogs the CC. Just thinking out loud.

I would be surprised if anyone on this forum has clogged their CC with stock (lean) jetting. If anything the addition of a slip on will only lean out your bike.

Cats rarely get clogged, and if they do it usually after heaps of miles and too much very low speed running, such as peak hour traffic. The Italian tune will keep it all nice and clean.

That looks normal and actually, clean. Previous generation of GSXR 1000 did had issues with the cats, I remember a few on this website and a friend of mine had it happen to his bike as well. On those bikes the cat would get clogged because it melted.

Trust me, the power loss when something like that happens is pretty noticeable, as in my Daytona 675 would outrun that GSXR 1000. He had a full system installed and they dynoed the bike before and after... Because of the clogged cat it was only making 80hp, less than a 600; so if happened to your bike you'd definitely notice it.

Thank you!

I'm one of those! It was caused by an after market QS on a standard exhaust. You see, all GSXR from L6 back are not designed for quickshifters, and if you add one on a standard exhaust the unburnt fuel between shifts may clog the cat, even dislodging it in some cases, causing it to move around and block the 3/4 pipe at WOT. That's why you should run a full system if you're using a QS. It doesn't effect L7 and above because they're designed for QS. I ended up gutting my cat and using Woolich to reflash.

Wouldn’t say that cat looks bad tbh. The current gixxer does melt cats if you map them on stock headers though FYI. And with prolonged track use also on stock fuelling.

Yes you can definitely notice the power difference, just came back from the dyno running too rich and made 102hp max, Also got chopped by a 600 yesterday lol. So I’m just gonna wait till I get a full system and get rid of this junk box of a cat.
