Down pipes

[Gazbo]

Back to the top of the subject. I got my stainless downpipes from sandybikespares (ebay). They have been spot on so far (about 1500 miles), BUT... the header gaskets, although appearing to be fine quality, keep freeing off in the bores( I suppose they are gradually collapsing down, and then they rattle in the slot when below 3k revs.Seriously - it sounds like you are about to drop a rod ! I Tightened studs a bit more ( even though I had given them a proper Post heat cycle re-torque). It cured everything for about 1.3k. Gradually it has come back to haunt. Tonight on the way home, as I passed parked cars, the reflected sound was akin to someone shaking a bag o' spanners next to me ! Tightened again. Cured again. I'm now well off the torque setting. So I won't be doing it any more. The garage said I should have put OEM seals in. Well you just don't do you. not when these came with the pipes. But I'm gonna - next time it rattles. So in a nutshell - the pipes are fine. I was not overly impressed with the gaskets - that's all. And if yours suddenly sounds like Cozy Powell riding his  hi-hats when he's pissed - take a breather. Might not be a rod. or cam chain tensioner etc.etc. Just check the exhaust nuts are nipped up propperly first! Careful - Not too much though !!!
