i just installed my helix(no catt) downpipe and mated it with my apex-i exhaust
now it seems by the radiator cap theres coolant/radiator fluid on it
never happnd before
this is an 03 wrx i checked theres no leaks anywhere everythings tight and legit
is this something to worry about or do i have to upgrade my radiator plugs?

any inputs good

thnx
chris
