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,

I dont understand this at all, perhaps I'm missing something? How can that "wee bit of power" (in a response) which "however I am sure there isnt a difference in reality" be a "good mod"?

Lets say its 0.5HP, that equals ~3% more power...for the price of removing the cat, which 100% guaranteed removed the environment protecting effect, and in a few countries would make the bike illegal to boot. At least it was free haha.

Sounds like the worst mod I can think of. I must be missing something...

EDIT: redundant post.
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:).
So you reckon this will get me ~2HP? Sweet!! :rolleyes: Thats better than a slip on AND a PC/Juice box!

the people that make/enforce the laws are always more obsessed with them, than those who have to abide them.
I would hope thats true haha :).

If you ever get pulled over just dont tell the cop that you gutted your cat, nobody will ever be any wiser. SHHH our secret. Sorry had to be sarcastic.
And when you sell the bike as Mike pointed out? I guess its okay to dupe someone and lie or just "forget" to mention it...:)
