alright so i'm using a helix downpipe but my check engine light is on. i heard i need to get a cel fix or something... i can buy one i guess since it's only $15 but is their any other way around this or do i have to order the cel fix...?

 

buy an AP, it will defeat that and youll be happy with the increase in power

 

yea i know the accessport is GREAT cause my friend has one on his wrx and it made a huge difference but for now i just need to get the check engine light off and stay off.

 

buy the CEL fix if you don't want to go the COBB way.
