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
