Hey everyone, Ive been searching around and Ive seen other similar threads but I need a straight answer. If I put a megan s-pipe and mid-pipe on and keep my stock headers, will my car still pass its emission test? And will my check engine light come on? It'd be nice to hear from someone who has either had or still has the s-pipe or mid-pipe (or both). Thanks.

 

you won't have a cel. whether or not your pass emissions depends on if you have a visual inspection of the exhaust or anything.

when it comes to exhaust, the CEL is caused when you swap the stock header for an aftermarket header because it removes the primary catalytic converter and the o2 sensor in the s-pipe detects the defficient cat and triggers the CEL.

just replacing the s-pipe and mid-pipe won't change anything really.

 

Alright, sweet. Thanks for the info man.
