I ain't used it myself but from numerous rave reviews (on here) I'd have no problem recommending the Eddy "performer rpm". It's a square bore/dual plane. As said it is very tall. The street dominator is a spread bore single plane with a real low profile & it gets pretty good reviews also. As said just reuse your bolt on brackets. Other good choices were mentioned. What do you have on there now? You mentioned weight so I'm assuming you have an OE iron one & in that case I'm sure you'll gain with an alum choice.
