The Hindle pipe that was recently pictured on this site wasn't what I would call a "performance pipe", is had NO merge collectors, it didn't even have equal length pipes. When mentioning"racing heritage" to recommend a product, one would clearly expect a "race' Style pipe...? It may have a slight gain in performance by having less restriction, but using racing heritage is misleading, I'm specifically referring to the Hindle pipe last pictured on this site , even good street pipes have merge collectors... I'm not saying that Hindle don't produce some good pipes, Mike Reick has a proper performance Hindle on his bike, its just that the only one I saw lately for a SOHC wasn't whats clearly recognized as a "performance" pipe...
