Roger I think I'm close to 20 oz full on my cat. I still love semi big nitro. I gotta go pic tomatoes ,were canning. Pickles are done. I help my brother out. I'm the skinner & picker. I wasn't happy with pipe length on the .45 rigger. So here I go chopping pipes. Glenn's new .45 header is nice as they get.
Tom the water cooled .21 header was on E-bay
