HERE I HAVE FOR SALE.... A Pair of High Quality Pi manifold link balance tubes. Made from polyester reinforced rubber compound for a long life. These fit in between each manifold, and balance and deliver idle air flow across all three manifolds. These can be fitted without removing the manifolds, as the tube is very supple. Price is for a pair (x2) of tubes that will suit the early single balance manifolds. If you require two pairs (x4) to suit the later manifold, then purchase 2 items and postage will be calculated at checkout. Please Note.... It is not necessary to use jubilee clips to attach these pipes... Vacuum and gravity is sufficient to keep them in place. THANKS...     TRIUMPHSTUFF...
