so i installed the ceramic dc header and after 4 hrs the CEL came on. how do i get rid of it ? and is there any way i can pass emission test with this since there is no catalyst.?thanks

 

1. get a defouler
2. put the stock one back in when smog time comes around or find a shady shop to pass you

 

Thats gna suck because it took me about 4 hours to install this header and id say il never do it again..

 

Ok so after i installed the DC header i didnt notice for a while that there is a hissing or idk what to call it but there is a noise coming from the flex pipe/right by where it connects to the exhaust and its a little loud. could it be the flex pipe?and if it is the flex pipe would i be able to replace it? or could it be the 2.5 header going to a 2.0 piping? or? It has a really nice deep tone its just that noise that idk if its normal.. thanks guys

 

Since it's a race header, you can hear the gases passing through the area that used to be the cat. It's normal, but just in case, double check under the car to make sure you don't have any leaks.

Are you going to run aftermarket or filled motor mounts?

 

defouler... and your good as for the sound thats normal but check for leaks...

 

Get flashpro and turn off the 2nd O2 sensor. You removed your cat and wonder if it will still pass emissions.....your seriously joking right?

 

Ok il leave it maybe il get used to the sound but il need a catback soon and then flashpro and i guess il just go to stock header when emissions come then put the dc back on.
