Stillen Long-tube headers are shipping...

OCtitan99 · 12-20-2005, 11:18 PM

I called in to Stillen today to see if their long-tube headers are ready yet. They told me that they started shipping yesterday. They are made of 304 stainless steel and with the headers and exhaust you can expect well over 20 hp....with the addition of an intake even more so...apparently the three together are very effective. They have a good price too...$699.00, just a little bit more than the JBAs...and you get more out of them. Most importantly, THEY DO NOT SET OFF CHECK ENGINE LIGHTS!!! They have not been tested yet with the supercharger so as of right now, just like any other headers, if you have the supercharger and warranty, it will void the warranty that they offer. I'm getting mine a couple weeks into January...Christmas is always a drain on my bank account...

Great! Cant wait for your pics and review.

From the picture I don't see any bungs for sensors. And since the cats aren't built in what are you going to do about them? The headers look good, but it's going to take a lot more work to get the sensors and cats installed.

I was able to view these in person and noticed the bungs were located in the collector.

Are they T-304 SS? If they are T-304 SS and without yhe CEL issues, they are a better choice than the Mossy_Chris headers selling for $850 on eBay.
I think with these headers, we may have to install hi-flow cats in place of the resos/2ndary cats and relocate the secondary O2 sensors further downstream after the cats. Any other thoughts?

Just a quick question, what are the advantages of a long tube header over a a short tube header and vise versa?

OCtitan99 · 12-21-2005, 07:27 PM

These are T-304 stainless Steel....There are bungs built in so there is no modification required, and you will not need to add any sort of hi-flow cats. These are labeled for "off-road use only"...it's a truck...I plan on taking it to Glamis...that's offroad enough for me...As far as which is better and what's the difference between a long-tube and "shorty"...First off long-tube headers are always better no matter what the situation is. Long-tube equal length headers make more power than a shorty header because they allow the exhaust gases to enter the collector in a smooth flow...also...the JBA headers are designed to work with the stock catalytic converters. Cats are very restrictive. Catalytic converters put a huge block on your exhaust system...kills performance. I will let you guys know how the install goes and how the fit and finish are when I do it in a few weeks...happy holidays to everyone...

Are These Headers 50 State Smog Legal ?

"Offroad use only" Means that they will not pass a smog test.

That's the 1st questions we Californians need to ask. Header's are just way too much work to install to have to remove them every 2 years for smog.

Does Stillen have installation instructions for these headers?? Install time estimate??

rico387 · 12-22-2005, 07:55 PM

Shorty headers are not really headers. They are performance manifolds. Header design with equal length primary tubes and getting collecter length right takes a lot of engineering, math, trial+error, and probably some voodoo. I did a lot of research about general header design and found so many theories and facts that I ended up with a pounding headache. Collecters too short...no torque. Too long...less revs. Shorties, Tri-Ys, 180 Degrees, Anti-Reversion, Step Tubes...AARGH! As I understand, stock Titan manifolds are some good flowing pieces. In some cases cast iron ain't that bad. Anyone remember the old Corvette Ram horns? Wanna really throw a monkey wrench in the gears? Take a look at this extrusion porting link. Tell me what you guys think. I'm gonna go get a Goody's powder. Think I'll wash it down with J.D.

I know that some companies offer similar services for the old 300ZX cars. Supposed to give you good results and great flow. Just out of curiousity...anyone with JBA headers, can you take a look at the side of the header that is stamped with the CARB certification number??? From what I understand CARB is not a big fan of cutting factory components and welding them to aftermarket....but if JBA can do it, more power to them...

There's no such thing as a long tube header that's smog legal. Not for CA folks that is. We have the most strict regulations in the country. If it's a long tube style header, it will definitely NOT be smog legal.

I disagree. Removing the catalytic convertor is not always the best way to improve performance. With a good aftermarket performance exhaust/header and a free flow convertor, the amount of power to be gained by totally removing the cat as opposed to running one would be very small. I'm not sure how well the factory cats flow, but today's aftermarket convertors flow considerably better than the ones made just a few years ago. Even factory cats are more efficient and better flowing these days. In some cases, a big exhaust with headers and no cats can cause slower performance by reducing the amount of scavenging from the cylinders. Reduced scavenging usually means a low-end TQ loss which is usually bad for performance on heavy vehicles like our trucks.

Anybody got theirs yet? I was also wondering about install time, real world, do-it-yourself type of driveway install time. Thanks.
