cat out

Hi there, new to this forum.
i want to take the cat out of my system? good idea or not?
and where can i buy a bypass pipe. i'm in the UK.
Thanksalot

I would go with a high flow cat or a resinator. Using a straigh pipe might make the sound shitty and/or louder than expected, and not to mention it might be illegal (dont know it it is were you live) and you know no one ever breaks the law.... oh wait.
