340R Colin's Exhaust.

[Gourlay83]

Colin's looking for some advise on the exhaust system for the 340R (Honda). As he struggles with reading and writing, i've volunteered to post (and i'm sick to death of the phone calls). For those who don't know the car I carried out a Honda conversion using the Stark mounts and driveshafts, with a local exhaust fabricator making a complete custom exhaust system.

The problem is the exhaust manifold, the primaries keep cracking. Have done since the system was made, lasts a few weeks/months then cracks. Exhaust fabricator has now washed his hands of it, on the grounds that the mounts are too soft and causing the failure. I don't agree with this, and believe it's clearly not fit for purpose where most of the weight of the system is being supported by the welds on the primaries but don't want to dwell on that (not my argument, or reason i'm posting).

It's pretty clear the exhaust's scrap anyway, my question is what to do now ?

Can anyone recommend anyone who makes custom manifolds north of the border, i've found plenty that make 'systems' but when you mention a manifold they quickly shy away (and wouldn't trust them tbh). Any recommendations/experiences would be much appreciated.

Might be worth speaking to Hofmanns (Chris Randall) - they have had exhausts fabricated for their race Europa. They now sell Chris Tullet exhausts that were made to their spec.

Already spoke to Chris Tullet, really helpfull and excellent quality. He would only re make the complete system (changing the design), which I can understand. Sadly this would mean Colin tailoring the car to Englandshire and another £1500+ bill and collecting in a weeks time. So would prefer to either tweak the original design or get someone local to re make to save cost but it still might end up at Tullets.

If he intends to keep the car for the long term I would suggest he really does consider going to Tullet for the exhaust. It will be money very well spent.

The only other quality exhaust fabricator I know of is Hayward & Scott but they are based in London, they may however be able to do something so still worth giving them a call.

Not exactly handy but meercat exhausts in kilbirnie are top notch at what they do. I've seen 24hr le mans cars in getting full systems and he made all the exhausts for colin mcraes prototype and personal cars.

He was 350 to make a manifold for my Evo using thicker wall tubing as they too are prone to cracking as they hold the turbo up

No idea if it includes manifolds but was very knowledgeable when I used him.

Thanks,

I'll phone around and see if anyone can come up with a solution.

what about one of these.

Link didn't take me to an exhaust, but assumed that's what you were on about. It wouldn't fit a 340R (silencer on top) and it's a good £600 more expensive than a Chris Tullet's system.

I wonder what the difference is from the exhaust that jim made for my 340r 5/6years ago and it's never had an issue to the one Colin has?

I wonder if it has bigger bore? Thinner material?

Apart from that it must be down to the mounts?

[campbell]

Hayward and Scott are providers of the infamous "Scoobysport" exhaust, I believe. An awesome addition to any Impreza so I'd be phoning them too

Quite simple - larger primaries, larger secondary, not the same design and the back of your old car looks like the forth road bridge with all the struts (no offence meant Sanjoy, yours works ). Where all Colin has is a 6/8mm bar on two mounts. I don't think he has even driven the car or measured any movement either. It's pretty funny to me, as following you or Mike in a 211 the engine moves SOO much but have a flexi/spring mounts to allow it.

Plenty of other people use the mounts with no issues, infact most say they're too stiff (hence why the car vibrates on idle and acceleration). I could post pictures to show what I mean but like I said, not my argument. Just trying to get a few places he can go to, try and get a solution for a reasonable amount.

P.S He's also done 30,000 miles since the conversion

Good on him, quite a hardcore commitment in a 340

Never used them personally but meerkat used to do all Colin McRae's cars, and they are in Scotland, maybe worth a call?

I am using the original sinclaires system, now heat wrapped and +100bhp, I don't expect it to last
