PLM EL HEADER BRZ
 

just install PLM el header, with Injen air intake, no tuned yet, another pipe all stock, when i start the car, the sound the same as OEM, but when i go to high REV like more than 4K, there is much more sound than stock, i will upload video asap, just need to find some place to test in west LA, too much traffic and cops, and i dont test it in apt or house area

That's an equal length header

Lol I'm think equal and I type UEL.... Omg, bad English

I search thread said Catless or catted will cause CEL, but I didn't, why? And on idea what is Catless or catted....

Plm doesn't have a cat. It will show a cel without a tune.

Catless and catted refer to the catalytic converter, which is a kind of filter for the fumes your engine makes. Catless means no catalytic converter. Catted does.

Ok, I see, so mine is Catless, thanks

header sound
 

Definitely get the OFT. I also just installed the PLM long tube header, and I think Shiv's stage 2 EL tune will be a big improvement. Let me know if you have a buzzing at 3000 RPM, or if the 3000 - 4000 flat spot is present. I have an automatic BRZ and I'm adjusting my tune for 2 things; to get rid of the flat spot, and to remove all stutters/hesitation after making manual shifts. I got rid of the after-shift hesitation, but there is still a bit of a flat spot. See here, https://youtu.be/Qcz-XJCMOUU

You need to put it through its paces, I give it 6 months before something on the header fails. Cracks
