im going to be using a gsxr k4 1000 for my new build do i need to add a cat before the exhaust for the iva man or would an original tail pipe be enough

cheers

cant see you meeting 2012 emissions without a cat

any ideas where to buy one, second hand would be more ideal as it would just get sold on again

we hire a cat for £50 which is built in the silencer.if this is any good for you please send me a u2u

thanks danny

danny i have recently bought one of those silencers 2nd hand do the cats come out easily as i dont need it?

Can't help with a cat but be aware bthat the new MOT regulations will mean a car that should have a cat and doesn't will be an automatic failure
