Tubular exhaust manifold.

Has anyone fitted one of these to their mk1? I'm just getting my car back on the road and have one that I bought from the u/s a while ago.It certainly looks nice, but just wondered if it will make any real difference? It would be with a magnex back box.Don't know what make it is, but may be hks? Thanks.

We have an equal length header on our SC and with the S/Steel exhaust system the car sounds awesome under load (almost like a spitfire)

I have also recently bought Chris (Limey's) blue HKS (?) Manifold to put on the N/A. Can only make it better me thinks

standard manifold is extremely good, and won't offer much of a restriction up to around 170bhp I thought.

Greddy.

Not sure about performance gains with these, may be a couple of ponies.

Thanks Mate

Can never remember these things

Reminds me... I need some more exhaust wrap. I want to try fit it this weekend

Get some relective insulation gubbins for the starter motor and shift cables as well. I have some of the bits I fitted if you want me to chuck them in the post for you.

How did it sound on the car?

I had a Greddy one on my Mk2 N/A, it was a few years ago now, but I still remember the awesome mid range roar it used to give

Cheers Chris

Let me know how much

How necessary is it? The standard system gets just as hot, is protected by heatshields. But there's no extra bits on the starter/shift cables?

Our SC's manifold is not wrapped nor is there any other reflective heatshields elsewhere. Something we need to remedy me thinks

It's only a couple of bits of reflective cloth one which I stuck over the heat shield on the starter (belt & braces

) and the other I wrapped round one of the cables which is very close to the manifold IIRC. I did end up knocking up a bracket to move the cable away from the manifold, I'll chuck that in as well (forgot to bring it up with me

).

PM me your address (again

) and I'll send them up.

can be good to 200bhp+ in some cases. indeed it is a very good design, especially for a cast iron affair

Since fitting my stainless manifold, my MR sounds like an absolute beast when under load. I would reccommend having one just for the sound!!!

they look good too...

are these the manifolds ive seen advertised on eBay for £129 or is that something else?

Anyone got a link?

System-G · Post by **System-G** » Wed May 16, 2007 8:54 am

The only ones I have seen on ebay recently are turbo manifolds designed for Corollas. They won't fit the AW11 without modifying the firewall. I'm not convinced of the quality either...

I have tried searching for a similar manifold to the one that is on our SC and the Greddy one I bought from chris, but can't find anything...

erm....yes it is G - theres loads or wrapping of something on there i think

Mine's an OBX stainless mainifold for an N/A corrola, i got it from the USA on ebay for about £150 including shipping. it's got an O2 sensor port on it too, which you can add an air/fuel sensor into or bung it up.

I've been told by the garage who originally worked on the engine before I bought the car that the standard exhaust manifold is quite restrictive once you get into about 170bhp plus region. I'd have to disagree with it being a good design anyway - if it was a good design they wouldn't all crack on number 4
