knightmaric Posted July 10, 2012 Share Posted July 10, 2012 I know this may have already been covered but I couldn't find anything.Will the cat, centre section and back box from an MB6 fit an MB2? Only reason I ask as my centre section and back box have rather large holes in them thanks to the roads up here and my cat is making the most god awful rattling sound ever.Now the problem also is the bolts on the cat are apparently seized to hind hell and will only come away from the centre section by using oxysetalyn *no idea of the spelling* but not many placed here deal with that.So if I was to go to a scrappy and find an MB6 would the full exhaust fit?

knightmaric Posted July 10, 2012 Author Share Posted July 10, 2012 Thanks for the info noodles.As the entire exhaust system is a bit knackered i'll be looking to change it all in one go.I think my main concern is the mb6 cat lining up with the manifold ahaEDIT:One thing I would also like to ask, can anyone explain why my cat is rattling?I can't tell whether it's the heat shield of the honeycomb inside of it.It only rattles when it's been idling for a little while or goes in a certain rev range.

simpo Posted July 10, 2012 Share Posted July 10, 2012 Prob the heat shield around the cat Quote Link to comment Share on other sites More sharing options...
james Posted July 10, 2012 Share Posted July 10, 2012 take the cat off and shake it its simple Quote Link to comment Share on other sites More sharing options...
knightmaric Posted July 10, 2012 Author Share Posted July 10, 2012 I wish it was that simple haha if I could get the cat off I would, but basically the boltd "in typical Honda fashion" have corroded away and the only way that they will come off so i've been told is by using oxy acetylene or something to heat up the bolts to then remove them.

james Posted July 10, 2012 Share Posted July 10, 2012 forget that .. use normal bolts/nuts with the springs just duble up the nuts so they tighten against themselvs Quote Link to comment Share on other sites More sharing options...
knightmaric Posted July 10, 2012 Author Share Posted July 10, 2012 As soon as I can I will, it's just getting the cat off in the first place aha Quote Link to comment Share on other sites More sharing options...
noodels Posted July 10, 2012 Share Posted July 10, 2012 use a hex socket smaller than standard and hammer it on as corroded away Quote Link to comment Share on other sites More sharing options...
