Ok I need some advice...

I've bought a 3" centre pipe just because it was cheap. Now im having doubts that it will actually fit as i have the standard downpipe assembly and a Ninja BB. So am i right in my thinking that it def will not fit?

 

I think the standard downpipe (cat) has a 2 1/2" end fitment.
My downpipe start which a 3" pipe which then tapers to a 2 1/2" fitment to the centre pipe.
I am not 100% sure whether it's 2 1/2" or 2 3/4" diameter end fitment.

 

Standard is 2.5

 

it needs 2.5" flanges but can still be 3" bore

what make is it ?

if its blitz then no cuz they are 3" flanges to back box
and your ninja is 2.5

 

The centre's a Scoobymania one
