saml666 0 Posted May 10, 2006 I will soon be lowering my Mi16 engine in, it has a reangled exgaust manfiold so I wondered where people best advise to cut and re-angle the downpipe to meet it properly? I guess right at the top maybe? I'm sure its fairly obvious when all in place but would prefer to get any advice before I rush in Cheers, Sam Share this post Link to post Share on other sites
j_turnell 137 3 Cars Posted May 11, 2006 If the manifold has been done properly you shouldnt need to cut and re-angle the downpipe... Share this post Link to post Share on other sites
Kev-G 1 Posted May 11, 2006 If the manifold has been done properly you shouldnt need to cut and re-angle the downpipe... Nonsense....By changing the angle of the manifold (re-angling) then the orientation of the manifold outlet to downpipe is changed.... saml666, Remove the complete flange from the downpipe @ the welded join to leave the pipe with nothing attached....Bolt flange to manifold (with gasket) and then offer up the pipe. Mark, tack, remove + weld completely.... Share this post Link to post Share on other sites

Man3 0 Posted May 11, 2006 I have a cut and re-welded manifold and my std downpipe fits fine. Share this post Link to post Share on other sites
Ryan 99 Posted May 11, 2006 I think it's pot-luck. Sometimes they fit, sometimes they don't - depending on who did the manifold, which make of downpipe you have, phase of the moon, etc... Share this post Link to post Share on other sites

Its not nonsense as we do this on all our conversions at 205parts and have no problems. Share this post Link to post Share on other sites
saml666 0 Posted May 11, 2006 Cheers guys, the re-angled manifold is of unknown origin so will see what happens, if it needs readjusting I'll do it right at the flange as advised Ta all Sam Share this post Link to post Share on other sites
Higgy 0 Posted May 12, 2006 Hi Sam, Look here for pictures detailing my downpipe modification: Higgy's Downpipe Mods If I was doing it again, I would take about 35mm off instead. My car had OEM looking 2-piece system. Higgy. P.S. I used QEP re-angled manifold plate. Share this post Link to post Share on other sites
