Do you guys do a Twin Throttle Body on the one side I thought I saw one on here at some stage?

We did, unfortunately we no longer manufacture or stock these twin throttle body manifolds due to lack of demand. Also, we have found that by fitting our intake manifold insulators and spacers as well as our 69mm throttle body you get approximately 90% of the gains of the twin TB manifold but for about 20% of the cost when you take into consideration that the twin TB manifold needs to be custom tuned.
