Hi,
I cut my stock pipe off my 2007 gs500f this weekend & going to be installing a new Yoshi slip-on pipe. After cutting the pipe off I notice about a cm in the exhaust there is what looks like a honey comb inside filling the entire area.
Is this the Catalytic converter?
Before I install the slip-on shoud I drill the honey comb out of the exhaust? What would be the pros & cons of doiing this?
Once I install the slip- on I will take it to a bike shop to do a dyno test.
Thanks

Yep, that is a catalytic converter. It really will not affect performance either way. It will help with emmisions though, burning off any excess fuel. Will not smell as bad too. When I made my undertail exhaust using a Duc 999 midpipe, it had a catalytic converter and I left it.
They put cats on GSs? Since when??
Thanks Dgyver,
I thought it would add some HP to the bike if I removed it. But if you say it will not change the performance of the bike then there is no reason for me to remove it.
Thanks
Fletch
Hrm, and I just finished reading an article on why they didn't put cats in motorcycles; something about the vibration and stresses that would break the ceramic.
I'm thinking that article I just read is full of it.
Fletch,
Any chance that it's still accessible enough for you to take a picture? It would be good reference for those of us who haven't cut apart our exhausts yet :icon_lol:
I will take a picture of it tonight
Fletch.
Apparently, they only put them through 2004 onwards. FYI.
It is quite likely that 2004 coincided with newer EU emission regulations. Given that Suzuki bored out the Bandit to 650 cc and then introduced a whole new FI engine to comply with restrictions, I find it remarkable that lean jetting and a cat did the trick for the gs500.
bit odd to find a carbed bike with a cat in it. but the emissions regulations are getting stricter, so all that can be done to reduce emissions is being done to our bikes.

Not really. The 2000 Kaw ZX9R has a cat in it. Last year it was carbed.
Any chance that picture's ready?
I have a picture, but do not know how to post it. I can send it to you by email if you want.

Actually, I thought only the CA bikes have them
