cant remember the exact design i just know they leave the engine as four pipes. go down to two for the joint half way down. then go underneath as two same as the supersprint then end just after the sump as one bigger pipe... 4---2----1... they are a different length to the cento as the clear the engine. but dont take much modding to fit.. ive seen quite a few running them.
are you needuing a new mani or are you makeing yours longer by welding a spacer in?

its needing a spacer in place due to the old spacer deteriating now so 2 options are new spacer or the bigger maifold but the p75 manifold has a 2 hole output which means a new downpipe aswell

yeh use the 75 downpipe and it comes out as one hole at the same point the 1108-1242 ones do...

Im going to try the thick gaskets on the old spacer first, that will bulk it up to 14 or 15 mm amd seal it better only issue i have doing that is the bolts on atm are useless and the standard fiat Studs are too short to go through everything to get a nut on the end
P75 would be better, but getting a downpipe? Van someone give me an easier mission? Lol

IF the gaskets is 4mm-5mm, it will get compressed once bolted... i think it will then only be 2mm or so ?

Yeah thats what i think too, the gaskets are 3-4mm thick so one either side of the spacer should give 2, maybe 2.5mm clearance both sides hopefully bulking the spacer up to 15mm
It'll either work brilliantly or be a disaster haha

just spotted them on ebay this moment, ermmm, i'll pass for now
was looking round the scrappy today for 75's, all they have in are 2 60's and 1 85 16v
i hate how the car i want is always on the top of the pile aswell
just for once i'd like them to make it easy hahaabyss113 said:yeah all fair saying use the p75 manifold are you gonna give the 50 bucks for the downpipe
Cheaper than a £200 John ashley mani

not as cheap as a few £ worth of gasket though. no point over complicating matters when chances are the engine could be binned in the summer anyway
Are you using 10 mm spacers just now>?
Just read ealier post saying you are, you know you need 2 gaskets right ?
Also did you extend the studs that is coming out of the mani?

thought yuo said you had the punto 75 mani..... id class the down pipe as one peice tbh lol. sure there is one in my scrappy for £10 for the entire thing... lol. will have to check i suppose

the 75 isnt a 4-2-1 manifold, it's a 4-2 manifold, it only goes to 1 in the downpipe which is part of the exhaust tubing rather than manifold. if it can be seperated it's not one part

yeh i just count them a one peice. as with SS manis they cover it all as one peice. lol just me though
OP
OP
aye, defo get where your coming from, you are kinda right but the ss mani is one piece to do away with the need for a seperate downpipe so it maximizes the angles of the branches as they wouldnt meet up to the standard exhaust otherwise
fiat decided to do it cheaply and stick a joint in there and use seperate pieces standard though lol

IMO, that is classified as a 4-2-1 mani.
