i know there are alot of advantages such as power and sound to adding a test pipe, but would there be any disadvantages? would the o2 sensor get clogged up and send wrong signals to the ecu?

 

Foulers ftw. Disadvantages? Car sounds like trash and everyone knows you have test pipes. Lol. Including cops. California has strict laws and in field inspections, tests. If you're not in CA, do it. If you do, go for it still. Straight pipes is ftw if you don't have Smog. Has a good flow and better sound.

 

IN Corona CA so don't do it. Unless you want sent to a referee.
