Who can get me 4 4" flare ports? I'm thinking about staying away from regular pvc.. Plus they look a little better..
depending on the flares. precision ports yes but I have some flares that seem to only be 2" of total flare, but they are not long enough.4" flares account fo 3" of length each. Therefore, if you need 15.5" total length... then then actual length of the tube needs to be 9.5"
