you are able to get away with that over there in the Czeck Republic.... we have laws here in the US that prohibit us from removing it. think it is about $2500 fine if you get caught with a tampered catcon.

i read about alot of tuners/off roaders who empty out the catcon. i thought about doing that to my H2.
buti'd prolly just get rid of the cat and run straight pipes to the muffler.

im all about getting the most performance, so if/when i do it, it will be when i put in new headers and a new exhaust system.

Well look here is the best way as I did it ok the H2 has to Cats ,,,so one at a time take of the front pipe that hold the cats now this bit is important the bulge area where the cats are make sure you cut into the cat from the top i.e. open it up cut in so you can wedged open like a flap from the top of the cat take out the brick filter ,,,push back the flap weld it up put some little paste round the weld ,,their you are the cats look like there still there ,,no one can see that you have de cated them as you cut in from above easy

prolly easier to just take the cat system off and use a pry bar or a pipe and hammer and just crush the ceramic in there to empty it out. ya maybe a little more work taking the system apart, but no cutting or welding
