Im assuming the headers (exhaust manifold) from a V4 would fit a V9 ?

And then the up pipe also same fitment.

Single scroll pipes.

Anyone?

No, they're not the same -the new age ones have a lambda sensor in the manifold, which the classics don't have!

Only learnt this myself a couple of weeks ago.

As already stated version 9 cars have a Lambda sensor in the collector which versions 3, 4, 5 and 6 cars do not have.
93-96 cars have bulbous headers with a Lambda in the collector.
97-00 cars have slimline headers, no Lambda sensor in the collector.
01-05 cars have slimline headers with Lambda sensor in the collector.
All headers are interchangeable MY93-05.
Uppipes. Generally the STi has no CAT in the uppipe and the WRX has a CAT.
