can you use a 1.1 down pipe on a vtr?

[logic_guy]

can this be done? Both are 8v so i guess so but i was wondering about the pipe diamater. Is the flange that connects to the centre pipe the same size as a vtr? Like for like fit?

Flange is the same on the centre pipe but not on the manifold as you've got a catalytic converter in yours so would need the 1.1 manifold too.

Guessin this is your idea? Cheap de-cat? lol

After finding out id need a different manifold I just bought the four branch

so the flange on a 1.1 that connects to the centre pipe is the same flange size and shape they use on a vtr?

I ask because my raceland manifold flange that connects to the centre section is wrapped. I'm going to chop it off and replace it. Its all in my progress thread what i want to do.

Thanks
