Hi Nolan,
Is that the 1300 UK manifold with the single downpipe or the 1500 with the
twin pipes? The latter is extremely troublesome with downpipe gaskets blowing
every 3000 miles or so. I've no idea how efficient it is, just a warning to
anyone who's tempted to seek out a UK spec manifold,
Cheers,
Bill.
