Been chatting with John from John Ashley exhausts in Walsall who can make up some manifolds cheaper then super-sprint.

He has got an ebay account with some items on name is johnashleyexhausts.

They are made to replace the puntos manicats so would need another adaptation made up to fit it onto a cinq

the ones he has on ebay are aluminised mild steel with powder coating (will burn powder coating off)

1.2 8v 4-2-1 ------ 170510790903 ------- powder coated finish
1.2 8v 4-2-1 ------ 170519314333 ------- aluminium coating
1.2 16v 4-2-1 ------ 170577890046 ------- powder coating finish

He is able to make up the 1.2 16v manifolds in Stainless steel for £235 with 48 hour delivery these are made to order, id say that's a dam site cheaper then super-sprint is charging for the 16v manifolds, also ends in a 2" bore


you can contact him though his site to get it done, with a 48 hour on postage

his site is http://www.jaex.co.uk/

this might upset custard but il soon see :p

yeh ive herd of him doing some race systems. if its good quality stainless and its the exact fit its worth every penny and saving a massive 140 quid on the supersprint
 
I think it's very udeful, pirus may be ordering a SS manifold in the next couple of days but it would be interesting to see how these stack up against SS.

Doesn't john ashley specialise in performance/competition exhaust systems?

Thanks

seeing as he can do custom exhausts id guess so yes, other thing to note the 16v manifold ends in a 2" bore rather then im sold 1.75" bore on a SS manifold which is a bonus

should be stickied this thread obviously left open to allow contributions to it
 
Mines a bit bigger than 2 inch as my system is 2 inch. The manifold has a reducer after it, think when I measured it, it was 65mm bore.

Thanks

this is on his ebay site for the 1.2 16v manifold, he did say they can be customised so you can have it changed abit if needed such as smaller or larger pipes

Technical specification
CNC laser cut flanges
1 1/2" primaries
1 3/4" secondaries
Finished in 2" to suit a 2" system
Made in ENGLAND

Think I would prefer a larger bore to a 100/200 cell cat (or none :D).

Tempted on seeing what he could offer, to be honest. But would sooner go over with mine and see if he can provide a better design than supersprints already good design.

Thanks

Right Pirus has his maifold here with me, and all i'm going to say is you pay for what you get (n).

Not saying they are a bad buy but making the comparison to something that is made in actual factory, and something that is made in a garage is more than visable.

Here is the comparisons.

Comparison is the bends and joining.

Flange for the JA is made so it's universal fit for both mk1 and mk2 16v heads, result is a narrower porting with some intrusive welds (no problem, open up with grinder and clean the weld.) Next problem here is the flange, obviously upon welding metal warps.

anohter comparison of welds and bends (n).

Supersprint seems nice, open, and smooth when it comes to pipe joining

JA manifold seems quite narrow, and not as smooth, but where the mount has been welded on obviously they used too high a setting and has also welded inside the tubing. Again could be ground out.

I know this is like comparing the angel to a young pikey girl (chosen nicer wording for obvious reason :D) but you would expect a much nicer qaulity from somebody like JA with just as much reputation at stake than SS.

Flame me if i'm poking, but I still think SS would be the way to go unless your on a budget.

Thanks

It's likw what I said, visually it looks like a pikey and freddy kruger have met up, and had a party with a welder.

Internally the welding has pertruded, so that has lost some flow already. Some of the bends don't look as great as they should, far from smooth as you can tell by the last bend for the twin lower section, and the way the pipes branch together :eek:.

The ports are also smaller, and need to be ground out as i mentioned (due to the universal flange fitting).

At the end of the day though, if you can afford it and you want performance then SS is the way to go, if your on a budget adn just want better than standard performance, then by all means the JA mani is the way to go.

Thanks

Well just rung up John and he told me there shouldnt have been any welds that intrude into the manifold and the pipe work should be nice and smooth on the inside.
He thinks there may have been 'a problem in-house', perhaps (basically someones going to get a ass whooping). So sent him the pictures with supersprint comparision. He's going to take a look and if he thinks its not his usual top quality work (which it sure isnt) ill send it back and get a replacement.

On a future note to any who decide to use JA, when you ring up make sure you ask for John himself. The first time i rung up, he had gone for lunch and the guy i spoke too didnt even think they did mani's for Fiats.

Cheers
Pirus

I have to agree... john himself is a bit of a perfectionist... the other guys who work there are not so good... infact he left a few jobs on my exhaust system to the other guys and they ****ed it up so he ended up redoing it again hes self (they cut and flared the exhaust tip instead of the other end where it connects the rest of the system)
