i couldnt believe your mechaninc said that, they can get in alot of trouble for doing it but anyways just go out and find yourself a cheap ls1 cat, prob wont do anything to power or anything but they are apparently better then a high flow cat?? thats what i read somewhere anyway

an ls1 cat has more monolith inside it, its cheaper than a highflow but it isnt as good, i tried them for a while and had alot of problems with it scraping on the ground due to the shape of it

a pipe bashed down the middle of a cat gives the deep note back.

about this 10k fine, how can they issue it when you could go out and buy a car with a hollow cat and have no idea it is hollow, then get done for it. plus i have never heard of anyone ever being fined 10g for a hollowed cat, has anyone else? is it a myth law to scare people or is it rarely enforced.

If you want to be a boy in the bubble in 20years time with your own oxygen pump do so, but don't **** it for the rest of us, The exhaust emmisions if every car was 'cat'`less in 2 years we'd have no O-zone layer.

Do what you like, You **** up it's your own fault.

Cheers
