Well I already have the ATAK Axleback, and was planning to finish the rest of it with Borla which was why I was asking. I just didn't feel like mixing and matching manufacturers for the exhaust.

I thought about just getting the shorty's and then running the pypes o/r pipes and cut outs for the track

I just put these on and what a difference, check the testing results!

What do you think the difference is likely to be in terms of labor hours, LTs vs. shorties?

They are both ball busters , but easy if you drop the k frame! Im gonna replace my catted x with a stainless works off road x, and will pick up another 25 hp with it.

Thanks for the link!

I really like the looks of those.. they look like standard long tubes, but cut off a little higher than the normal ones..

You mean mid-length headers?

Long tubes, shorties, or even replacing the stock manifold all take the same amount of effort.

My personal car has the stock "headers" with a JBA o/r x pipe, a magnaflow competition cat back exhaust, and a steeda CAI... which put down 426rwhp/395rwtq on a mustang dyno... One of our customers' cars has the BBK shorty headers, bbk x pipe w/ high flow cats, the magnaflow competition cat back exhaust, steeda CAI, and a boss intake manifold, and it put down 437rwhp/380rwtq.

Obviously the main differences are that his car had cats and mine didn't, and he is running the boss intake manifold and mine is stock. But for gains of only 11rwhp and a loss of 15 lb/ft of torque (which I account to the intake manifold) I'd say that shorty headers aren't worth doing. Get the LT's or don't get anything.

Shortys that get u 25 hp with the cats and a high flow x or h are worth getting so far only kooks gets that power! Kooks are a better product then bbk!
