Hi Guys,
Does anyone out there knows about exhaust headers for Sidekick 1,6 8v?
Do they offer what they promise or not?
Is there the possibility to increase the emissions of the car after installing a header?
-
I got a Calmini header on my Tracker, and I noticed a pretty big power difference when I put it on. I'm running 31's and I don't have any probs going 100km+ down the highway.
I'm not sure about emissions. I live on Vancouver island and there aren’t any emission laws here so I wouldn’t know if it changed or not.
-
It seems that your emmisions would stay the same, as long as you keep your stock exhaust system... but I don't know for sure. Pure conjecture.
-
Thanx a lot guys.
What about RRO (Thorley) Headers vs Calmini Headers?
Has anyone tried the Thorley?
-
I am not sure about the emisions, as headers need to be carb approved to be legal for the street, and the Calmini is not, not sure about the thorly, I have heard they were made by Thorly for Calmini. The Calmini header is top notch and dirt cheap for a header, price out headers for Hondas $ 400.00 easy.

I was really close to passing my emissions without my cat. I run the Calmini header (16 valve) and 2" exhaust with a magnaflow muffler. I had to weld the cat back in to get it to pass. I was soooo close without it. With the cat in it makes the grade by a mile. Oh ya, and the power difference between running the cat and not, is unbelievable

Calminii the ports match up perfect!

Without it has more power I presume

What about the second o2 sensor after the cat... or do I have this wrong and you had more power with the cat.
-
On 8v engines, there is no O2 sensor at the cat.
-
so you get more power w/o the cat?
-
Generally, yes.
More flow = better performance
-
Generally, yes.
More flow = better performance
Yea but my thought was with the 16valve their is a second o2 after the cat. If it were to read rich (from removing the cat) wouldnt the computer lean it out?
???Mike
-
Would it read rich if you removed the cat, but replaced the O2 sensor back into the exhaust system? Or could you just unplug it, or would that cause some adverse affect?
-
What abou Hawk headers?
Fredo
-
Mike, the reason you have an extra o2 is because your 97 is OBD2 which moniters the cat. If you take the cat out you will get a check eng. light with A code p0420. But that won't effect eng. perf. The front o2 sensor gives the rich/lean command.
Later,

I think I will just leave it alone. ::)

Yesterday I had a chat with calmini's tech dept. And I asked them about the legality of their headers.
They told me that the calmini header is not legal in California, because of the optical inspection.
And when I asked them if it affects the emissions of the car, they replied that it doesn't affect at all.

OK SO WHO HERE BELEAVES THAT ;D
-
It is correct, the header is a Thorley header minus the carb warm up pipe, that would mount to the exhaust manifold, and will not pass C.A.R.B. without it. Take a look at the Thorley header and you will see what they are talking about.

I have the Hawk header, i like it alot. It deffinetly gave a little more zip. Plus Hawk make them with 3 (i think) different coatings, so you can get the fancy racing ceramic stuff if ya want :D

i just finished installing the calmini header and i have to say throttle respones is improved quite a bit, man i have to say these little 1.6l engines just running off the header can be quite LOUD but i had to go for a rip with just the header HAHAHAHAHHAAH :o ;D :o
