ok, i just finished putting in my spoon n1 muffler and skunk 2 shifter tonite and i go out for a late night test ride. I come home and i see a puddle of radiator fluid slowly pouring out. I check it out and it is comming from the bottom of the radiator where the aluminum meets the plastic. I was driving it pretty hard too to test the muffler (which sounds awsome) . My 98 R has only 46K on it should it be leaking already? Do i need to replace a new radiator? Thanks for the help guys!!

 

This is a common problem with honda radiators. Both of my previous integra's had this problem except it was at the top. Just replace with an aluminum one or an aftermarket all metal one.
