Never again will i remove an exhaust collector from a MKII.
finally after TWO years of dealing with "life", i got back to my 86vr.
lost my "religion", 14 times, before i got the blamed thing off!
NOW! if you haven't had your MKII collector off, you might need to do a double check.
mine has rusted out/through, about 3/4 of the circumference on ALL 4 exit pipes.only option is to take it to work and fabricate all new connections.
one good thing!!!!!! my baffles are all still good!
lol
just jt
