those are shorties and shorties don't gain you much hp/trq on the modular engines. If your going through the hassle to buy and install headers, go for Long Tubes, gains of 35+ are not uncommon.

 

Correct. I gained no hp or torque from shorties, and 30hp, 35ftlbs from my long tubes.

 

well i ordered those for my truck, and im getting them put on in two weeks. i think it has to help quite a bit, at least for my application the 4.6. i've got hi flows x pipe and dual imcos, i think these headers will be a good addition. these are a affordable solution rather than spending all that money on longtubes, then having to re-fab your whole exhaust as well. and if you have the 4.6, well longtubes are only offered by pacesetter.
