I'm about to install my new header and fab up the exhaust. But I need a flared section of pipe that will mount to the donut gasket. The piece of flared pipe I have now is 2.5" but it doesn't flare out enough to mate with the gasket. Can any of you recommend a place that sells it for a fair price? I'm heading to the local muffler shop tomorrow but if they don't have it, I'd like to have another option. TIA

Btw, here's some pics of what I have now for reference, as you can see the pipe doesn't flare out enough even though it's 2.5" in diameter:
