Hi Guys,
I’ve put together my own exhaust and for some reason I’m having trouble getting a good seal on the manifold/downtube joint. They are SCP 2.25” downtubes and the manifolds are ported out to 2”. The downtubes came with the pipe seam still on the flange so I already ground that down flush with a file. It doesn’t sound that bad but I can put my hand up around the flange and feel the exhaust leak on both sides. I cranked the nuts down as tight as I can go. Any suggestions?
