Well, I got impatient and fitted the Spoon 2-1 section yesterday. I ended up just reusing the gaskets as they were in decent shape. Used a bit of high temp sealant too and so far so good, no leaks.
For reference, the fitment of this is perfect as you would expect from Spoon. Quality seems very good and it's really woken up the noise from my Rm01a. The car barely sounds any different at lower revs but give it some and it really wakes up, gives off a nice howl. I have a feeling it threw a flame earlier as I let off in 3rd. There is no EML showing but I reckon its over fuelling bit. Could really do with K100 now though to get the best from it. So far however, all seems good ðŸ‘.
