ahh... well I think handbags has well and truly smashed that with the 1:16 he did in big red at Sandown. Don't see any of the RWD boys beating that soon!
the muffler possibly will fit, I'm not familiar with R32 exhaust layout. It has a right 90degree mandrel bend off the muffler, 3.5" all the way. Fits R34's, unsure about other models.
