Sorry should have read that properly there is only 1 cat on early imports (at least) and that is the downpipe.

The old bill can pull you (http://www.glass-uk.org/index2.php?o...o_pdf=1&id=267) but it all depends how loud it is.

my mate was followed and pulled over for having an exhaust not to the officers liking 9HKS super drager with decat) and was warned that next time he would get a section 59 next time.

You should not be worried about setting alarms off mate, your car you do what you like with it
I live in a cul-de-sac and go to work just after 5.30am and i don't give a s*@t what neighbours say or think
