on my indy exhaust (R1 engine) wher the four pipes meet the collector to reduce it to 2 there seems to be a terrible rattle when revving over about 5k! any suggestions on this apart from bashing them further together with a big mallet!!
cheers,kev

my bro had a problem like this,it looks like theres 4 inner pipes spot welded in the 4-2 section and one had come undone.
