I want to get them further down the road, when stillen stops sending out defective headers.

Improper install, improper tuning, improper setup is what leads to situations such as this. No idea what kind of car you had, or what it was tuned on, etc. A properly selected/installed/tuned set of cams will not have ANY stalling, or any other driveability issues. Our engines are not "more sensitive" (I don't even know what that is even supposed to mean) than any other engine out there. It's an engine...if you want to make significant power on it, especially NA, cams become part of the equation by default. Whether they are worth it as a standalone mod is of course debatable, and that is up to the end user to decide for themselves. Cams are an integral part of the recipe.

Nitrous is certainly another path to go for those who want it, or even nitrous + cams, which would yield even greater results. Like anything else though, correct selection of components, install and tuning are the key to a successful nitrous install as well. At the end of the day though, it's not a zero sum game - for some, nitrous is just not a desirable way to make power (I know it's not for me, and while I'm sure I'd net huge gains, it's just not anything I want)

as you said... PROPER TUNE. and I guess more a mod become "exotic", less are your chance to get it done right.

the 350z community goes for nitro or TT setups, or just basic bolt ons.
how many people have a NA full tune or built? you and kwame.. AFAIK. and how much time you spent in research, trial and error.. and get information from racing teams in japan with that kind of experience? (and racing is again a different game, because of regulation, what you can and can't do..)

that is a different story in the corvette community... cams are one of the popular mods.... you'll find a reliable shop able to install and tune it w/o any problems.

Anyone who thinks headers are not a worthwhile upgrade, as I have said before, is ****ing retarded.

That's a great increase in power/torque across the board. There's gains EVERYWHERE, some places seeing as much as +15whp/wtq. ****ing awesome man.

I had an E36 328, put in E36 M3 cams (the exhaust had a little too much duration hence the cold start issues). The car had lower compression, a less aggressive tune, and any number of other things that made cams less volatile. The variable valve timing system on the HR is a much bigger pain to mess with than the old single vanos my BMW had.

I understand the importance of cams pretty well, the valve train, intake manifold, exhaust header, and combustion chamber shape are your 4 key players in making power NA. Most shops I wouldn't trust with installing the cams and getting a tune set up...

Wow. You can REALLY feel the power. Like the other person said before, the peak numbers aren't much, but holy s***. You can really feel the difference through out the whole powerband. I never would have thought these headers would create this much difference in power. I strongly recommend getting these headers as a bolt on upgrade, they are SICK. *Except for the defect, that blows.*

As I said, use the right part, and have it tuned properly, and such issues simply do not come up. While I realize it's often easier said than done, your issues were do significantly to the fact that some/all of these ingredients were missing. We have 2 BMW track cars, so I'm very familiar with the I6 engines, both M and non M series. The HR engine is really not anymore complex than any other engine out there when it comes down to it, and a natural evolution of the DE, which has been torn apart and modded significantly over the years. I understand what you mean about not trusting most shops. I've been there before over the years myself, which is why we do all the work to our own cars - I simply don't trust anyone else to touch the car, and am lucky that we have people in house that can do virtually anything needed (plus I have another car, so if it's not done on time, it's really not a big deal). In this community, crappy shops exist across the board, but we're also blessed with several very good shops throughout the country, who know these cars backwards and forwards. While they might be a touch more expensive if you're not local to them (travel/shipping costs), they reward their customers with a tech/service level that many enthusiast communities don't have at their disposal.

^i was under the impression that you guys don't build customer cars anymore, is that right?

i know that DE headers will mate up with the HR with the only catch being you have to use DE style cats or test pipes. Might be able save quite a bit going that route instead of shelling out for overpriced HR headers and test pipes/hfcs

correct - been that way for years and years now - we only work on stuff we own in house

and damn my spelling errors!!! We NEED the edit buttons back!

shame, you guys would be the ones i'd go to for a cam install (in the distant future)

btw, edit button works for me, and its been working, i never noticed it gone

Could very possibly be a very smart idea. Either way these headers are awsome and the car is whole new beast with them. ALl you have to do is get over the peak gains and these are great.

This might sound weird but, I wanna see if your headers do it too. Does it sound as if you can hear the air flow through the headers from inside of your car, almost like a slight exhaust leak? I know it sounds weird but I swear I hear it. Also when i floor it, I feel as if I can hear the air flow through every single header tube at the higher rpm's. Like the pitch goes up and down when im accelerating, its weird.

infinite

I know what sound you're talking about... it's a snake sound lolz. I heard that on my other car when I installed a header
