I really don't like the idea of my check engine light being on bc of the o/r xpipe. But if the high flows don make that much difference in sound and more air flow then it's not worth it. That's what I need to know.
Do you have a SCT tuner? It's just a matter of spending 2 minutes tuning the car and you won't have any engine codes. Although I ran my O/R h pipe for a few days before tuning and I Didint have any check engine light.. Not sure if this is normal or not?
