Stillen Headers installed - Review/Pics/Vid/Dyno

kdoske · 08-04-2009, 09:40 AM

Same thing happened with my last car. I purchased some headers and had them installed and the low end torque went bye bye. It really did suck there was only a small power increase and that was above 5000rpm. I took them out within a month and my cars reponse was much better.

Not to say that headers can't make a car better but I think what has been said above is pretty much dead on for most vehicles these days.

I don't think the headers are a negative. And with tuning they may turn out to be more positive than they seem now, too. It's just not worth the installation hassle (or cost, if you're paying someone else to do it).

That's true. They may pay dividends with a tune. It'll be hard to tell though, because one would need to do a tune w/o headers for a baseline, then do another tune w/ headers to get a comparison number.

on my sentra ser spec v, after i installed my header it made quite a bit of differance. install was pretty easy too, which is to be expected on a 4 cylinder. didnt notice any torque loss and noticed a gain in hp. maybe because the stock exhaust manifold on my sentra is so much shitter than the exhaust manifold on the 370z?
