I have done some pretty extensive searching on the forums about this topic. I have my manifolds off right now and have already started porting. I have the lip at the collector gone on the passenger side, nice and smoothed out using my die grinder and stone bit. I have seen on here where people are opening the collectors up to two inches, Inside Diameter I guess. This is quite a bit of opening up. My question is, if I go ahead and do this, how will my stock downpipe fit? Will it be too small and leak? I cannot afford to by new downpipes (larger, if someone makes them). What should I do?
