GreenVTi991 Posted January 16, 2013 Share Posted January 16, 2013 Hi guys,I'm not happy with the manifold currently fitted to my Civic - a DC Sports 4-1 (designed to fit an Integra). Not only does it sit very close to the oil sump, it keeps splitting along the weld where the four branches join to one. I've had it welded once before and could get it welded again but I've lost faith in it and would rather not have to take it off once a year to get it re-welded.I also find it too 'boomy' in the cabin (I also want to change my 4" jap tip to twin 2" exit)I'd like to change to a 4-2-1 with a 2.5" collector and sports Cat. I've seen a few brands bandied about and would like your opinions on them:DC Sports ceramic coated or stainless 4-2-1 (Not sure I like the flange connecting 4-2)Tegiwa 4-2-1Toda Racing 4-2-1Blox Racingor Ebay specials ranging from £75 - £180...

simpo Posted January 16, 2013 Share Posted January 16, 2013 IMO I think the 4-2-1 isn't good enough for the 1.8 I think the tubing is smaller compared to the 4-1 Quote Link to comment Share on other sites More sharing options...
knight Posted January 16, 2013 Share Posted January 16, 2013 Depends what you want from the mani? top end power or mid range power???? Quote Link to comment Share on other sites More sharing options...
GreenVTi991 Posted January 16, 2013 Author Share Posted January 16, 2013 I like the sound of lower down power. I doubt I will feel much difference day to day Quote Link to comment Share on other sites More sharing options...
knight Posted January 16, 2013 Share Posted January 16, 2013 I like the sound of lower down power. I doubt I will feel much difference day to dayso 4-2-1 is the way to go! Quote Link to comment Share on other sites More sharing options...

GreenVTi991 Posted January 17, 2013 Author Share Posted January 17, 2013 Ooh interesting and tempting. My only concern is will I have clearance issues like I have at the moment seeing as it is for an Integra??An option I'm looking into is getting whichever manifold I choose ceramic coated. Is anyone running a ceramic coated manifold? Quote Link to comment Share on other sites More sharing options...
NIKH25 Posted January 17, 2013 Share Posted January 17, 2013 I have a 4-2-1 supersprint on mine and there are no clearance issues, it shouldn't be a problem as the engine externals are the same afaik, perhaps the one you have is just an oddity.
