and on the subject of longtubes are the only way to go... no they are not. it depends on your application. for your n/a run of the mill mustang, yes lts are best. but for a high reving centri car, unequal length headers will PWN lts any day of the week, as far as gains.

What I don't understand is why when I called Roush to ask about headers for my 427R and if I'd have to have the Roush ECU re-flashed, they said that headers won't do anything as far as hp gain. How is that possible?
