A cooper freeflow from Maniflow and a 1.75" Maniflow twin box system is going to be you best bet.

[Cooperman]

Actually a 1.75" int. dia. system is a bit too big for an 850 unless it is a full race-tune engine.
The best bet is an original 998 Cooper system including the 3-into-1 ex. manifold and single box exhaust system. Thatvwill give a good exhaust gas velocity without it being as restricted as it is with a standard 850 system.

where would be best to buy from ?when you say 3 into one is that not the lcb ? sorry not that clued up on this ...any links would be really useful

[valve bounce]

a simple effective and cheap mod would just to cut one of the boxes out of the standard system.

anymore suggestions anyone ?

[Duncy H]

I'd recommend a system like the one you have posted a link to. The cooper freeflow manifold and rc40 work well together with the smaller bore engines.

[Cooperman]

The closest you can get to the original 997/998 Cooper exhaust system the better it'll be. The Mini Spares web site seems to be down at the moment, but you could give Richy a call at their Harrogate shop, 01423 881800, and ask for his help. I'm sure he'll know what is nearest to the original and he'll give you a good deal with some TMF discount.

hmm... looks like between cooper freeflow & rc40 ....or orig cooper 998 & 3 in 1 so far....

anymore 850s out there with a set up to recommend ?
