stillen headers legal or illegal?!
#5
The Stillen headers are not currently CARB approved - they are apparently still pending. They will pass the sniffer test, however.
The general consensus regarding anything short of a supercharger or turbo is that if you have stock cats, you will pass the sniffer.
The Stillen headers add over 10whp and something like 18wtq - which is not insignificant. However, most people see header installs as "not worth it" because you will pay a lot for the gains. There ARE gains though...don't let anyone tell you otherwise. If you are doing the install yourself or have found a shop to do the install for relatively cheap (like 2-300 bucks), then I'd say it's worth it. A lot of guys get $1000 cat-back systems that don't even give them half the power gain - but you never hear anyone say anything about the return of investment of that mod.
There are too many people on the forum that just "bandwagon up." They see other people say headers make no power or aren't worth it, and they just spit that information out on any relevant thread to boost their post count.
I had DC Headers installed during my engine swap (so install was free) and the DC Headers are CARB approved. They make less power than the Stillen headers, however. I paid $450 for my headers shipped to my door off Amazon, and just handed them to my shop (who ironically, is Stillen themselves) and they installed them.

* Stillen is the same company that claims that kinda HP gains with there intakes which we all know is incorrect!

Gains with headers on the DE engine are minimal. You need to add cams for anything worth while. HR is a different story.
Where in Buks county PA??? I'm from the solebury/Doylestown area and I'm moving back to PA next week. I'd be happy to help where possible.

as far as gains, OP has an '03. that means nonRevUp. nonRevUps do not make "worth while" gains from any type of header, w/o aftermarket cams. RevUps can w/stock cams and tuning.

Your wrong, because PA is one of the states that follows CARB standards. So his statement is valid. States have the option of following Federal EPA standards or california CARB standards. CARB standards are more strict. If the headers were CARB approved with a carb number he could legally run them in PA since PA follows CARB.
If they don't have carb numbers, you can probably still run them but it'll be a gamble whether or not the smog tech will notice or not.
