lgoedert Posted December 17, 2013 Share Posted December 17, 2013 Hii would love to see a picture of the 6 Branch Tubular Exhaust Manifold Stainless Steel from Rimmer installed in one of your cars.And what are your opinions? Quote Link to comment Share on other sites More sharing options...
garyf Posted December 17, 2013 Share Posted December 17, 2013 I've no personel experiecne of one of these Manifolds but have read that the 6 into 3 into 1 Manifold flows much better and gives increases in power and torque when used in conjunction with other modifications, i.e. modified cylinder head, larger Carbs and performance camshaft.It really depends on how far you want to go and how much you have to spend with tuning? Do a search on this site there is pleanty of good advice and I'm sure someone on this site will have used one of these manifolds?RegardsGary Quote Link to comment Share on other sites More sharing options...
lgoedert Posted December 17, 2013 Author Share Posted December 17, 2013 Dear Garymy manifold and complete exhaust system was of no use anymore, the manyfold had a crack in it. Yesterday i wanted to install the manifold but on the left side, the first tube is about 4milimeters too far to the right in order to fit....My tuning is already done with a 2liter engine in a vitesse from 1965.

garyf Posted December 17, 2013 Share Posted December 17, 2013 It looks like your manifold is incorrectly manufactured?All I can suggest is you contact Rimmers to discuss, they're a reputable company so should be able to exchange for a manifold that fits.It looks like another case of poor quality parts :-/RegardsGary Quote Link to comment Share on other sites More sharing options...
npanne Posted December 17, 2013 Share Posted December 17, 2013 The build on most of the stainless offerings is variable, to say the least. Mine (a 6-3-1 Phoenix unit) was an absolute s0d to fit as one of the primaries comes out far too close to the stud - so close in fact that the nut doesn't have room to turn (one of the flats is pressed against the manifold), let alone get a socket on there. I can also see from dry-assembly that I'm going to have problems with the 3-1 joint as it's not tight enough to seal, but there's not room to get a clamp on it.

JohnD Posted December 17, 2013 Share Posted December 17, 2013 The pic at the top of this thread is of course not a 6-3-1 but a 6-2-1 which a completely different fish kettle. The first can take advantage of scavenging AKA interference to optimise extraction of exhaust gases. The second is no better than a cast manifold.Even then the primary length is critical. They must all be the same and the longer the lower the revs at which it will resonate. From memory 17ins gives a peak at three to four K.John Quote Link to comment Share on other sites More sharing options...
Steve P Posted December 17, 2013 Share Posted December 17, 2013 I have a Pheonix 6-3-1 and its a terrible fit,it sits too low below the chassis where the collector is,no experience of the 6-2-1Steve Quote Link to comment Share on other sites More sharing options...
Tim Bancroft Posted December 26, 2013 Share Posted December 26, 2013 As Steve states, the fit of these things is variable to say the least!There is a more expensive option, but too dear and availability is not great.Has the cyl head had some modifications done to it?

Nick Jones Posted December 27, 2013 Share Posted December 27, 2013 Not really.....There is a gap in the market between the £400 ish ones that are not a great design and tend to be a very poor fit (though you can get lucky) and the very nice ones that are over £ 1k.I'm also of the view that while you shouldn't expect the best design or highest quality materials at the cheap end, they should at least fit. If they don't, they are not fit for purpose.Nick Quote Link to comment Share on other sites More sharing options...

Given that it had storage surface corrosion, was up to about 30yrs. old - no warranty etc. In other words it's not as though it had been bought new from a trader....I'm sure it was worth the money - I've heard of Mike 'the pipe' Randall - but there was no confirmation that it was his handiwork.I concede that due to financial penury I have to run my dear little Herald on the most meagre of budgets, but am proud that she is able to now sport a 'stainless' exhaust....Were my financial situation better, i would not baulk at spending anything on her...in fact I've had to get a steering column joint replaced (upgraded UJ type) as the previous one (from a reputable trader) did about 6-6.5k miles & 18months!! I'm therefore well aware that paying for quality saves money in the long run........... Quote Link to comment Share on other sites More sharing options...
Steve P Posted December 27, 2013 Share Posted December 27, 2013 Can`t disagree with Nicks point about the current offering being not fit for purpose sometimes.The rear collector pipe on my one pointed to the ground when fitted for the first time,when i contacted the well known supplier they asked me to get the car there and they would cut and weld it,as they were 100 miles away this wasn`t really feasible so i did it myself.I suppose i should have rejected it as NFFP.The one on e bay may or may not be Mike Randalls work,it is definitely of his type though with decent sand bends and proper joints,i have a Saloon version of his which i am selling soon,its a quality piece of work.I cant wait to get rid of my Phoenix 6-3-1.Steve Quote Link to comment Share on other sites More sharing options...
Steve P Posted December 31, 2013 Share Posted December 31, 2013 Well it arrived this morning and it is a proper hand made sand bent manifold with good primaries etc.Well worth the cost and its goodbye Phoenix.Steve Quote Link to comment Share on other sites More sharing options...
Ridgetone Triumph Posted December 31, 2013 Share Posted December 31, 2013 MK 1 extractor sports manifolds have always been a poor fit since the '70's as I remember fitting some to the rally Vitesses and Heralds that were converted to 2000 engines with them. A load of twisting and forcing and sometimes elongating the holes for the studs to fit threw. Good to see nothing has changed ::) Quote Link to comment Share on other sites More sharing options...
lgoedert Posted January 21, 2014 Author Share Posted January 21, 2014 a final update:thx to Rimmer for the exchange, it fits now perfectly! Quote Link to comment Share on other sites More sharing options...
