An LCB

...and a Marina manifold, along with a sawn off Minor one, and an alloy inlet

Oh, so the Marina manifold is a single cast inlet/exhaust. I can imagine that wouldn't be much of an improvement over the Minor one.

If it doesn't work, you're not hitting it with a big enough hammer.

I have also been looking into getting an LCB manifold so i can attach my alloy inlet manifold and hs4 carb but after a chat with the Morris Minor Center in Brum it seems that Falcon havn't made them for about six months :( They are looking into getting another manufacturer but not sure when. I'm guessing that the Maniflow one is the only available LCB at the moment apart from the odd second hand ones that pop up. This is the only part I need so any other ideas guys?

They're still advertising them on their web site! :roll:

I know Alex, its mad. I must be a problem for quite a few people. Apparently Falcon make enough money from modern car exhaust systems to warrent the cut back on classic car products. Never liked there exhausts anyway :wink:

I should add that it's my assumption, btw, that it's a Marina manifold as it came with a car, so I didn't source it myself. The Marina downpipe fits it though :D

According to Vizard the LCB produces more power only above 4000rpm.

Tha Marina manifold has a larger internal bore. as mentioned earlier the Falcon single pipe system is designed to fit to this.
The Manifold system is desiged to mate to their LCB's and it may well prove to be the case that a Maniflow LCB won't fit a Falcon exhaust and vice-vesa.
Unless someone has done this - and can tell us that by a happy coincidence....

My exhaust is made from a 2nd hand LCB, a twin box mini rc-40 system, an over axle bend from JLH and a piece of straight pipe. It easy and relatively cheap if you get a 2nd hand RC40.

The exhaust section on an Ital manifold is exactly the same as the MG metro exhaust manifold (inlet was an alloy one). MG Metro exhaust manifolds turn up on ebay fairly often and someone on www.minifinity.com probably has one to sell. If I didn't find my LCB fro £16 its what I would be using now.

Not a wonderful pic, but here is my system

I think the over axle and straight pipe was £30, and 2nd hand RC40s can be had for as little as £10-£15 and they are stainless. If you have the option go for a center exit, however a side exit does work as shown above

JLH also does a modular type exhaust system where you can pick and choose what you want

Hope thats of use!

Matt, I was hoping to use an rc-40 single box side exit with a length of pipe connected to an LCB but if I can't get one then I might go for the metro manifold. LCB is preferred though. I'll stay on the hunt.

Hello all I have a rebuilt 1275cc (Midget, metro head) with the Hif 44, I have a Marina manifold 1.5" and a large bore S/S down pipe, which bring me to around the floor under the passenger seat. This is on a pick-up and I intend to exit just in fron the rear wheel passenger side any ideas what I can fit?

Will the Minor RC40 work?

I'd be grateful that Falcon have stopped making their exhausts. I had no end of trouble with it - so much so that they demonstrated exactly what they meant by 'lifetime warranty' which was 'until the 3rd one breaks'.

I have heard from a few people that the standard morris exhaust in stainless steel is allot louder than the original? is this because of a bigger bore? Is there any performance upgrade with this?

The bore is the same. I believe the extra noise is down to the material, by nature, being 'harder' and more resonant. When i replaced my old mild steel system with one I found it was about similar but then the old system was past it's best, obviously thinner and probably a lot louder than new.

Just out curiosity, how long does a mild steel exhaust last in the UK's weather?

Impossible to say really. It depends on the length of you journeys, state of your roads, weather, time of year, if it's a daily driver, where you store the car and which mild system you buy!
