Long tube Gaines, Is it worth it?

Most increases you see are from going stock to longtubes, not cat delete or offroad H/X to longtube. I'm thinking I might see another 20rwhp and am not sure it's worth it for that little.

I understood it that LTs on a FI car helped out much more than on a n/a car.

That is definitely true. Also work better on larger displacement motors. It is common place to see 18-25rwhp and similar torque on LS1s using 1 7/8s headers without a cam. I could see adding larger tubing if there was a big cam involved.

why are a larger diameter headers not worth as much on these cars? Dark Pony hit the nail on the head. These motors, while badass, are still only displacing 302 ci.

same reason a larger throttle body isnt worth anything.

How much you pick up from an aftermarket part is based on how crappy the stock stuff is. So the fact that one doesn't really gain a significant amount of power from stock is a testament to how good the stock stuff is. The other part of the equation is velocity.

Ill take a smaller primary tube header with a good exhaust velocity and keep my torque. we're talking about street cars here right?
