phill1975 Posted April 19, 2014 Share Posted April 19, 2014 know it might sound like a stupid question but you did put the sealing ring between the mani and decat didn't you I have seen it done before and they forgot to put it in rattled like hell but only at certain revs Quote Link to comment Share on other sites More sharing options...
Grant Posted April 19, 2014 Author Share Posted April 19, 2014 Decat went on at the same time Nick. Wouldn't be surprised if it's knocking a little as there is no play in the spring bolts at all. Wife has taken it to the gym ATM so will look at it when she gets back. Ah thanks for the heads up! But the design might help being that it's slightly baffled. Phil, yes I did get the ring in there, it was a pita! But either way, can't stay like it is, far too loud lol. Quote Link to comment Share on other sites More sharing options...

Have you got a 2.5" collector on yours? And is there movement on the spring bolts? Quote Link to comment Share on other sites More sharing options...
NIKH25 Posted April 19, 2014 Share Posted April 19, 2014 If there's very little play in the spring bolts you must've pulled the rest of the exhaust quite a way forward so it could be knocking further back. Quote Link to comment Share on other sites More sharing options...
Grant Posted April 19, 2014 Author Share Posted April 19, 2014 Yeah that could be it Nick. Although, even when the rest of the exhaust isn't attached there's no play. So I'm thinking that the decat end that links to the mani isn't big enough in diameter. Not sure whether to give in and put the standard mani back on, I have a couple of hours to play with it now so we'll see. Quote Link to comment Share on other sites More sharing options...
phill1975 Posted April 19, 2014 Share Posted April 19, 2014 mine has got movement at the springs sounds like yours might be touching somewhere can you get it to make any noise by grabbing rest of system and seeing if it knocks Quote Link to comment Share on other sites More sharing options...
simpo Posted April 19, 2014 Share Posted April 19, 2014 Did u take the bracket off underneath? Quote Link to comment Share on other sites More sharing options...
Grant Posted April 19, 2014 Author Share Posted April 19, 2014 Tried the grabbing and shaking, no noise. Just Aiken it all apart though and noticed that the end that meets the mani was slightly bent. So bent it back and have out it back together. Also think that as the decat (adjustable when bought and came in 3 pieces so welded to fit) is probably 10mm too short which is obv pulling the rest of the system up. Any way, put back together with adjusted flanges, will go out for a drive shortly. Dinner with the wife beckons now. Which bracket so you mean simpo?

KiNK43 Posted April 19, 2014 Share Posted April 19, 2014 Guess he means the bracket that hold manifold near O2 sensor. Some aftermarket mani don't use it. Some do. Quote Link to comment Share on other sites More sharing options...
