Does anyone know some nice performance exhaust manifolds for M20b25 engine??
S/S and equal length or tubular or whatever is best really
Thanks!!

That pretty much rules out the only one I would recommend, unless you can get one second-hand.

ireland engineering in the US sell a racing dynamics style manifold for about $850, & they say it fits RHD.
just checked, they are out of stock at the moment

I saw that as well, but would really like confirmation on that before ordering and shipping from the US.

Covered in great detail over the years
BTB is basically the only/best option if you want power. £1.5K+
If you Google Hartge E30 headers on Australian eBay, there are some allegedly Hartge/Alpina copies there...unproven but fit within your budget.
I'd be very sceptical buying from the US for RHD cars, especially with E46 Racks being common. Space is tight down there.

i know what you mean about 6 branch manifolds being covered in great detail on here over the years as i've read most of the threads.
as for that one i linked too be able to be fitted to a RHD e30? a friend of mine lives in the states & took his RHD touring with him when he moved out there a few years ago, i asked him about that manifold fitting as he bought one a while back when they first started to offer them & he said that it was a tight fit but went in without any problems,
i'm tempted to go for one when they start selling them again (but get it sent to my mate first then onto me
) as yes the BTB is meant to be the best there is but if can lay my hands on a racing dynamics style manifold for less then the cost of a 2nd hand BTB then i'll go for it.
just got to wait now.
