What's a good replacement for stock headers?
 

I don't really want to go with LT's. I'd just like a nice replacement for what I have now. I replaced the stock cats with hi flows and the flattened y pipe was replaced. Now I think it's time to replace the stock manifolds.

Any Opinions?

JBA makes a good stock replacement. Only about 11 horse gain on the dyno over stockers though.

Are there any midlength headers that will allow me to keep my current y-pipe?

No, I don't think there is unfortunately, although with a true 'shorty' header such as the JBAs or similar (but not Macs, they're mid length) you might be able to fabricate a way to make them work but it won't be cheap/easy.

I would go with Macs if i were you. Some will say shorties will give you nothing. Im not one of them. With JBA's you may pick up 10hp at best. Macs will be good for atleast 15hp plus if you go with a cam or heads in the future they will benefit more wile the shortis will become a contriction like your manifolds are now.
