Noz Posted May 21, 2013 Share Posted May 21, 2013 Why not just use a standard manifold gasket? Link to comment Share on other sites More sharing options...
Fly Posted May 21, 2013 Share Posted May 21, 2013 yea just use the gasket rather than paste. Apparently your not supposed to use exhaust paste before the CAT Link to comment Share on other sites More sharing options...
prosty Posted May 21, 2013 Share Posted May 21, 2013 Isn't the stock gasket just a press on gasket? Not a flange type? On USDM / Euro Turbos with decats, I'm not sure those works Link to comment Share on other sites More sharing options...
Suprakeith Posted May 21, 2013 Author Share Posted May 21, 2013 Cant use manifold gasket as not taking manifold off its a decat pipe to get rid of 1st cat and have got standard press gaskets all ready but have always been told to put bit of exhaust gasket paste or sealent to help seal the join as could have slight pitting in flange faces Link to comment Share on other sites More sharing options...
Noz Posted May 21, 2013 Share Posted May 21, 2013 Oh sorry my mistake. In that case it will be the 2 bolt connection. You can get them off eBay or recommend your local supplier for cheap as chips. Those connections are simples, there is no reason to use paste dude. Link to comment Share on other sites More sharing options...
berg Posted May 21, 2013 Share Posted May 21, 2013 Dont use gaskets i did and a few others have also on the first decats they seem to blow badly. I took mine off again and used loctite 5920 as reccomended by whifbitz and it no longer blows Link to comment Share on other sites More sharing options...
Kaan W Posted May 21, 2013 Share Posted May 21, 2013 I bought some gaskets from ebay for my 3" system and applied a thin smear of gumgum to both sides of the gasket. Gaskets alone will probably do fine but I wanted to make sure Link to comment Share on other sites More sharing options...
safcdixon Posted May 21, 2013 Share Posted May 21, 2013 I used Holts exhaust paste on my decats and my sideexit system, no leaks at all it sailed throught the MOT (with no cats in too) gaskets can be unreliable in my opinion Link to comment Share on other sites More sharing options...
Suprakeith Posted May 21, 2013 Author Share Posted May 21, 2013 Thanks for the advice have already got the three gaskets ready but wanted to be extra safe, will have look at that loctite as that sounds intresting and that holts paste as only want to fit it once dont want it blowing couple months later Link to comment Share on other sites More sharing options...
