Gutted Cat

I just wanted to post it up in case anyone else would be curious in the future. I gutted the cat on the stock pipe today using a 1" spade drill bit. It had that hard, more metallic material that was difficult to remove.

Difference in sound is hardly noticeable. I really cant hear any difference. So no worries in that department. butt dyno approves, however I am sure there isnt a difference in reality. good mod considering its free, cant really think of any foreseeable negatives, and pretty darn easy to do on the bike.

cheers,

to gutt the exhaust is quite a popular mod here in thailand.
it adds a wee bit of power and usuallly makes the bike a bit louder too(not much). we had a stock cbr and one gutted cbr and the gutted one was a bit hotter:)
it sure helps to keep the coppers away....
enjoy the ride

@ cbrdave
almost all mods hamper with the street legality of the bike - nothing new there.
we modders are some naughty boyz, however hard mom tried. are you a cop or what?
this world aint gonna end because someone gutts his cbr250 cat and you know it´s bs. take the cbr instead of your car and you do start to make a little difference.
happy riding
i´ve googled gutted cat - shocking...

you´re right about the "mods" mike lol

who says there´s no gain in taking the cat out? i say there is! we tested it with two identical cbr´s (one gutted....)
the gain is usually around 10% in cars and motorcycles
and it keeps the cops away from you:).
the people that make/enforce the laws are always more obsessed with them, then those who have to abide them.


cheers
