Larger crossover tubes

[brockw08]

This may seem a dumb question to many :bang, but what do they do? Any drawbacks to running them? And the biggest question: Where can I find some? I've looked all over the net for a set. Are they worth it? Price?

You dont need them for your setup.... you loose streetability.

At what point would I need them? Also, what causes the loss of streetability? Idle lope?

They have not really shown any HP gains in street applications. Imagine your fuel system like a big hose from IP to injector tip.... The larger xover tube will create a "bulge" if you will and without addressing the rest of the system, you are wasting $$$

I put some in my truck along with some bigger sticks. I didnt get to try them with out the injectors. Everyone says they have a lopy idle. ONly when i first start it up in the morning. I havent noticed any driveability problems. Everything thing seems fine. Its a cheap up grade. But like tim said you dont need them for your setup. Haisley machine has then. IF you do go with some dont get any bigger than a .093 xtube.
