I Have lts with ory pipe..NAd i installed two rear sims that I bought off a member and I went to go get my check engine light read for the first time since the sims,and I pulled 3 codes two for the rear and 1 for the front 02...So what the hell is wrong with the sims?or do they simply turn off the check light?

 

Did you clear the codes after you installed the sims?

If you think the sims are bad, send them back and I'll refund your money.

 

I got the codes read today and I have deleted the codes that came up..Im still waiting for the check engine light to come back and ill then have the codes read again hopefully only the front 02 comes up and not the rears...

 

well the check engine light came back...Im gonna get the codes read tomorrow,and if the rears still show up ill let you know and we can discuss the return if needed
