Ok I installed the dcrh, and wow i am impressed, well i did not have an o2 extension, so other then the check engine light do i have anything else to be aware of ?

 

yeah, you'll need to get ESSM inserts. our motor love to rock around and have broken these headers.

 

Yeah I know inserts are necessary, since the flex pipe on a race header tend to brake. I was referring to the check engine light, should there be anything I should be worried of ?
Thanks for your input "h8ted ek".

 

I'm not sure which is better performance wise but a torque damper would be good instead of or in addition to the ESMM's. Also, does your vtec still crossover with the check engine light on?

 

You'll be fine. check engine light does not effect anything besides telling you that your o2 sensor is bad.

 

yeah it still crosses over, now even louder then ever.


oh ok then i will keep driving until my shipment of my o2 extension comes lol.
