Is it welded together yet?

Not yet. Right now I've got work piled up to the moon, so the manifold is on the back burner until I can get caught up.

238,900 miles (384,400 km), that is a lot of work is it all paper work?

^ Plus the thing about being able to breathe.

No, I don't do paper.
I'm a sparky.

Hey Garm,

Injen sent out a good replacement tube, and the intake looks great!

It was late so I only got to run it to see if there would be a CEL. No light.

cali yaris · 06-07-2013, 11:03 AM

Looks great - I like the little shield.

tooter · 06-07-2013, 11:56 AM

I do too.

The design is very simple and direct. It's a whopping 3 feet long and actually very quiet. It's also easy to move around if I start messing around with the intake manifold.

Check out the header. LCE makes a really neato design that folds a long tube header into exactly the same space as the stock header. It fits like a glove!

^^^ RE: "long tube header" - Please forgive this noob question, it really is a question and not a troll, but why does it matter the length of a pipe? Don't you want the exhaust to just get out via the back of your car rather than in the engine bay?

Not my wording but makes sense:

Quote:

Exhaust headers with equal length tubes have been shown to develop slightly more power on an open exhaust system, but not when hooked up to a street system with mufflers. Fact is, most street motors with shorty headers will produce the same power as they would with expensive equal length headers.

Equal length tubes can produce more power, but they have to be the right length for the specific motor at the RPM range where you want the power. What that means is lots of custom fabrication and dyno testing, which translates into lots of time and money.

For racing applications, the slight gain may justify the cost, but competition cars can be more easily built "around the engine" than street cars. When you're working within the confines of a given body style and chassis, with motor mounts, starter, steering linkage and accessories to think about, the way the headers fit become more important.

That's where the compact or "shorty" style header shines. You get a significant performance increase compared to stock exhaust manifolds, at an off-the-shelf price..

Remove your header and see how much power you lose with no exhaust at all. A LOT.

I can attest to that

Well that's strange, I never would have guessed that would even affect the performance of a car. So exhaust pipes on the header make the engine work better rather than having nothing there to restrict... to me that's just really weird, hehe

It's all based on the Helmholtz principle, the Bernoulli effect and fluid velocity. Lots of crazy physics and maths to explain it, but not really relevant unless you're into that sort of thing. Here's my understanding of it: escaping exhaust pulses down each tube (Helmholtz), drawing a slight vacuum on the adjacent tubes (Bernoulli). Velocity and pressure of a fluid in a tube is decreased by increasing the diameter. Decreasing the pressure means easier flow, but lower velocity and less scavenging effect...I think.

I just got it because it looks really neato.
