Is the manifold (exhaust) on the 1.6 standard ford part ?

Yes - but there’s a few different types of standard Ford. I think Phil A posted some pictures once?

Yes, standard ford part. 3 variations fitted to the SS1 but all interchangeable.

I have new and second hand replacements if you require one.

Thanks all for replies, tempted by new one Philip don't fancy swap as old one been on for 27 years any point on stainless manifold on standard engine, if there is such a thing, also anybody out there got a spare connecting rod between inside handle and latch mech, with fixings at both ends ?

for my tuppence, although NOT a direct swap I thought that when I fitted the 1600i / XR3? exhaust (its a sort of four into two affair) the car did seem a wee bitty more lively, but maybe just imagination :-)
and i'm not using the top end revs . . .. .

there is a thread on here about the advantages of fitting fancy duffers, Phil (AKA RR) and the guys on the project progress have some pretty amazing looking bits o kit, shame that some options seem to need the removal of the passenger :shock:

As an upgrade the Xr3i manifold is better, but the standard downpipe is the main restriction for the CVH in the SS1. There are no off the shelf alternative manifolds that would work with the standard downpipe without it's modification but if you are serious then that should be the first thing to spend money on replacing.

could you be a bit more specific regarding down pipe mod for Xr3i conversion

The downpipe studs are in different positions, so you need to cut the top bit off the downpipe (where it goes 2 into 1), rotate it and weld it back on.

The flange needs rotating and about 3/4" of pipe chopping out as the exit flange is also lower.

But in my view it's a waste of effort to cut and shut the stock downpipe. You would gain very little if nothing at all from fitting an XR3i manifold WITH stock arrangement downpipe (modified to fit).

Pictures of my 1300 with XR3i 4 branch cast manifold and custom made downpipe HERE. Refresh page if pics not showing.

Aye possibly but in my case the gases were escaping from teh cracked manifold so there was a little to gain, but i agree if looking for BHP do extra work, if you have the inclination, I was only after an MoT pass and no questions from Insurance . . ..
