green diamond Posted September 20, 2019 Share Posted September 20, 2019 I have one new old stock genuine GM front pipe part number 90091862 to suit the 2.0 CIH engine as used on all the GTEs and Cavalier MK1, its a proper right hand drive pipe with the flat resonator box, in its original black painted finish with a weeny bit of rust here and there, its way to big and heavy for any courier service so its cash on collection from North Lincolnshire LN11, I cant post pictures but I can watsapp or email them if you send me a pm with your details, £140.00 Quote Link to comment Share on other sites More sharing options...
Vinyltop Posted September 25, 2019 Share Posted September 25, 2019 Morning, would you know if this will fit an early 1.9 coupé at all, please? Cheers! Quote Link to comment Share on other sites More sharing options...
green diamond Posted September 25, 2019 Author Share Posted September 25, 2019 Hi, it was used on the 1900cc coupe from chassis number 85002183 onwards which is about 1978 I think, if you not sure let me have your chassis number and I can check the microfiche Quote Link to comment Share on other sites More sharing options...
Vinyltop Posted September 25, 2019 Share Posted September 25, 2019 Thanks, I'll get back to you with the number 👍🏻 Quote Link to comment Share on other sites More sharing options...
Vinyltop Posted October 1, 2019 Share Posted October 1, 2019 Hi Green Diamond, my chassis number starts with 5, so I imagine it's well before that. Would your fiche tell you if the later pipe can be used on the earlier cars? Cheers! Quote Link to comment Share on other sites More sharing options...
green diamond Posted October 2, 2019 Author Share Posted October 2, 2019 Hi, let me have the full chassis number and I can check, send me a PM if you dont want to post it here Quote Link to comment Share on other sites More sharing options...
green diamond Posted October 2, 2019 Author Share Posted October 2, 2019 So the 1st 2 digits of the chassis number denotes the body style, in your case Coupe, your chassis number starts with 6 so like you said its an early car and the pipe we have will not suit, I believe the early 1.9 like yours used the same exhaust manifold as the 1.6 which had a different flange position or angle to the later 1.9/2.0?

cam.in.head Posted October 3, 2019 Share Posted October 3, 2019 no difference in manifold. all front pipes are interchangeable 1.6/1.9/2.0 .only real difference is larger engines had additional silencer in it rather than the 1,6 which didnt.hence put a 1.6 pipe on a 2.0 if you have to but it wont be as quiet. nowadays its a case of get what you can find. my 2.0 had until recently a 1.6 front on but with a silencer added into it .personal choice .

My chassis number starts 59, so even earlier! The manifold to downpipe flange is the larger one of what appears to be two different sizes - if the gaskets available are any indication.

cam.in.head Posted October 7, 2019 Share Posted October 7, 2019 hi. in all the cavaliers/ mantas ive had from a 76 with a 1.6 to 87 gte none of mine have ever had any differences regarding the exhaust manifold fitting flange or gasket.(all cam in head engines) There are indeed a few sellers on ebay selling gaskets which are not correct and are either for the viva chevette or cav 1256 which are a similar but much much smaller gasket or some seem to try to sell the carlton / rekord gasket which is shorter than we need. yours is a b series and a 1.6 front pipe will fit if you realy want but the 2.0 has the extra box which does make a difference and worth fitting to all (1.9 i think was available with or without the extra box depending on original or which aftermarket maker ? ) these exhausts do pop up on ebay from time to time and there are even some new ones on at the moment too ( a fair price thou !) or if you are ok with a welder and the actual branch pipes up to the manifold are ok its not too difficult a job making the lower section yourself.some people have no doubt gone down the stainless route or performance route but that a matter of personal preference as they can sometimes alter the exhaust tone from standard which i for one certainly wouldnt want.

The manifold to downpipe flange is the larger one of what appears to be two different sizes - if the gaskets available are any indication. The 59 at the start of your chassis number is the body style, 59 meaning Coupe, the chassis number is the next 8 digits and yours starts with 6 which may help later if your looking for chassis number related parts On 07/10/2019 at 17:49, gt/e paul said: Hi has this sold please?
