Get the rest of the exhaust done in 3" or sell it and get one that is only 2.5 the whole way. :2cents:

... is there anyway that i can connect the two?...
I mean this prolbem will exist even if i want to buy a megan catback.
the megan pipe inlet is 3" and the catalytic converter is 2.5". I've searched but i can't find a 3" inlet and 3" oulet for a catalytic conv.
so in short, i can't connect either from the downpipe's outlet or the catback's inet.
the only thing that is 3" is testpipes and i don't want to be caught.
so yeah...
another thing... if i have the 3" downpipe, and i bought the megan racing 3" exhaust system... so i just connect the two? or do i have to have a test pipe in the middle? can someone please show me a diagram of a complete exhaust system form manifold to muffler... I'm confused now.
