The hole is on the underside. And 1/3 of my 15,000 miles per year is in the rain. Syracuse, NY USA 13066

Btw how deep should i drill? ( about 5-10mm)
I'm curious also as to the exact drill spot, but I guess I don't take verbal directions all that well.
If it is not too much trouble, maybe you could use Paint to put a circle where the hole should be and repost.

I think it would probably fail an MOT test in the UK. As the exhaust is holed.

Would it work if the hole were drilled, tapped to a known size, thread and pitch, spray zinc, then plugged?

then the plug could be pulled as needed. Say for those heady days at Daytona...

I'll try this as soon as I learn exactly where the hole should be.

The metal of the can is thick enough to hold a thread or two but there is not a lot of room between the can wall and the cat to run a tap in if you do it on the underside of the can as I did.

Drill a hole in the correct place, weld a nut on around the hole and hey presto, no need to tap the exhaust ,and 4 or 5 threads for a plug.

I was on a 880 mile camping trip on my CBR250R last week. Maybe this weekend I can get a video up.

Just left it. It is pretty loud now. I might recommend going a bit smaller.

I didn't see the Honda sketch of the internals of the exhaust , but if I drill a 20 mm hole through the tail end of the exhaust and through the first chamber, won't I get the same gains with a neater appearance?
