Anyone yet to find a company that has a 4-2-1 Header for the Yarii yet?

Bis -- I could tell you if you blindfolded me whether there was a CAI on the Yaris or not, it does feel different. 70 to 75 hp is almost 10%, unlike my Scion tC, where 140-145 was NOT noticeable.

The only headers I know of are the Megan Racing and they are 4 to 1.

Just created my own look at the pics to see why I say "Part-time." It becomes CAI when the cooling fan turns on...
I have noticed a difference in the response of the throttle, initial take off and going between 65 - 80 on the Freeway. The sound is funny because it almost dies away completely after (about) 3000 rpms. CIP, I do not know if I want to go TRUE CAI or not with the simple mod I did. I don't see this vehicle being able to keep up with my old accord, but I won't be upset if I am wrong.

My low end is the same, the top end is slightly better. It now drives like it did with the stock wheels (it became noticeably slower with the 17s).

Cheers

As per the TRD parts pamphlet, a TRD CAI will void engine warrenty? anyone have any trouble from the dealers yet?

I guess I’m a cheap bastard, I couldnt pay $200+ for a CAI so following Chino’s design I purchased and XB Short Ram from Ebay, and with a machine shop at work, I just shopped to sides. It fit like a charm. Gains have improved trough out the band specially after 3rd gear. Here’s a picture of my GhetoSR.
