Attach Pipes to Headers

[byates2]

Hi there. I'm looking to do my own exhaust. I bought a kit from flowmaster and have a good amount of pipe with different bends to work with.

However, i am getting confused on how to attach the pipes to the headers.i have 2.5" hooker headers. I keep searching 2.5" 3 bolt flange and the only thing i get are reducers. I'm looking for a 2.5" 3 bolt flange with a 2.5" pipe outlet. I thought this would be a pretty common thing but i cant seem to find anything.

Am I searching wrong? How do i attach the 2.5" pipe to the headers?

Thanks
