my engine broke down in my 2002 gt and im buying a crate motor. i have to swap over the intake manifold and headers but the headers are all rusted so i wanna get some headers probably just shorties while i have it out to give it a better exhaust tone. im wondering how often could there be an exhaust leak? im going to be spending enough money on getting it fixed and dont want to keep fixing it. Also would it be worth the shorty headers or not? give me some ideas thanks

Don't bother with shorties. Either stay with the OE cast manifolds (a little surface rust is harmless) -- you could always media-blast them and have them ceramic coated... -- with new gaskets or go LT. You won't see any performance increase with shorties because they don't flow much better than the OE cast part and they lack the scavenging benefits offered by the tuning of long-tubes.

Before deciding on LTs make sure you understand the implications they have for emissions testing. LTs sometimes struggle with this because the thin metal loses heat so fast and the factory H-pipe (and its cats) are not usable with them. They can also make certain types of servicing tricky (e.g. transmission removal for clutch access). But they do offer the best power gains.

If the choice is between shorties or cast, I'd save the cash and stay cast.

Are there any LT manufacturers that have addressed this issue? Or do they all pretty much interfere with the transmission removal?

i use BBK ceramic coated LT headers and have no problems with them at all. Make sure you get new gaskets and stege8 locking header boats!

Everybody makes their LT's different. Therefore the collectors end up in a different spot. It probably won't fit.

Flowtech's use a different collector style than the Pype's H uses, so they will not fit together.

Does anyone know what brand h-pipe would work with them. I know flowtech makes a x pipe but id rather have an h-pipe.

I go with Kooks b/c of the trans service issue. X pipe will give a bit more HP than an H. Don't let the X pie vs. H pipe slow you down as far as a decision goes.

i heard that MAC longtubes can allow for tranny removal. I ordered a set and sent them back because of the quality of them....the welds were terrible.
