Daz, I think if I was buying aftermarket i'd go GRS!
Any idea what power/boost they are good upto?
will be running a 2.1 ZVH, Omex, Tubular manifold, T34, possibly throtle bodies, low comp pistons, 3" bore exhaust, BVH. (all going to plan anyway!)
was really wanting single pass and 3" pipework tho..I've got one in mind but need to find out if they are still available and if I can make it fit, all hassle tho!
