Are these out yet? More to the point-has anyone actually installed them and then run a dyno?

 

They're already out. I got the ceramic coat one installed but not yet dyno due to weather. But it won't help anyway cuze I got other stuffs on my car.

 

Did you feel any increase in power with the Stillen Headers? Any loss in power on the lower RPM range? Any substanial increase in sound/noise?

 

I don't see any loss on the lower RPM. Before I had the XERD long tube headers, there was a little loss down low. But with the Stillen it's easier to spin in first and second gear. As for sound, it didn't change much even with Kinetix hi-flow cats. Here is a sound file.

Got any sound clips of your setup under load (ie. in the car as driving it or outside the car as it drives by)??? It is good to hear the setup and how it sounds when the car is actually going.

 

I will do that as soon as the weather gets better. Right now my baby is in the garage . Just checked the weather and it looks good. Will do it tomorrow.

 

Well, I am interested, cause I do like your setup on the exhaust side. You can't really tell from sound clips, is it much louder than stock for the headers, cats, and exhaust?? Any droning?? I know that the borlas are said to be a quieter exhaust, can someone outside of you tell that you have the headers and cats on the car in addition to the borlas??

 

ARG! It's snowing right now so can't do what I promised . As for your questions, with the combo it just a tad louder than stock. No droning. People from outside won't know i have headers and hi-flow cats. Amherst/Buffalo winter weather sux big time. I can only drive my car for 5 or 6 months per year

 

I bought the Stillens and returned them. the welds and grindings were very, very sloppy. So I bought the Nismo headers and oh my god, talk abour perfection! You get what youn pay for.

 

Really? Is this the new NISMO version that Jason@Performance was telling us about? My NISMO ones look quite sloppy.

 

Yes, the new ones!!! They are awesome.

 

The stillen headers fit up really nicely...

We have a couple sets in stock...
