I am looking for some vilocity stacks for a crower injection system. I am planning on fabricating the induction system and want 8 bells, tubes, stacks, or whatever you may call them. I do not need the intake or other components just the bells. I believe my intake has 2 1/2" id holes. If you have any of these or know of anyone who does please let me know. E-mail tony@hydroplanesunlimited.com or post a responce here. I have seen these on ebay for $100 a set, am just trying to see if I can cut down the price any.Thanx
