Brozz 250: Poking the Cat

[tknj99]

Hi All,

I considered replacing the stock exhaust with the aftermarket option but am shying away for 2 reasons, fitment around airbox and possibly too loud

For those who have modified the stock exhaust, is it possible to get thru the cat to poke a hole and allow more airflox without cutting and welding?
I removed a cat from my previous bike - Honda Fury 1300 - and was able to accomplish it using a 12" or so drill bit extension.. could that work for our bikes? I wouldnt necessarily need to remove all of the cat, maybe just make a 1/2" or 1" hole thru it.

Also, did removing the entire cat make it as loud as the aftermarket, which ive read can be too loud or was it just right?

Thanks

If the Cat is located in the same place as on the Hawk you will have a hard time drilling it with the curves in the pipe.

Gotcha.. i may try to insert a thin pipe down the exhaust and see where it is and whether or not i can get at it with the extended drill bit or if i can figure on some kind of spear with a hammer maybe

It's located in the bulge right behind the heat shield on your header pipe.

Ah. scratch that idea then..
Let me ask you this, is there a center baffle somewhere near the rear can area as well or just the cat near the header section?
I read this from a previous old post: from Sochin - not sure if this also applies to the Brozz or not
and when he references center baffle, i wonder if he is referring to punching holes in the exhaust endcap, if so ive poked 8 holes in mine

I still ride with the stock Hawk exhaust/cat :O I did port the header pipe to match the CRC head I got on. And I punched out 12-14 holes in the center baffle, it retains my torque for mountains and I can still go 65-68 on flat ground with 17/50 sprockets. It still remains a very quiet bike, and I will keep it that way to make it easy to sneak up on wildlife :P.

Here is a good link on taking the CAT outa a HAWK.

I would not suggest drilling the cat, it's filled with cadmium, which is super toxic.

Good to know.. you'd think they'd at least put a warning on the exhaust

[Bruces]

You don’t need a warning if you just leave it alone .

True.. although once you catch the mod bug, it can be a tough thing to shake

[franque]

I think they don't put a warning on it because you're breaking the law if you remove it. That's why aftermarket exhausts are always marketed as 'off road' or 'race' use only.
