CODE P0134 and P0030

Hi guys,

After getting the stage 1 perrin tuned for a couple month my car at 3k miles got the first check engine light on P0134 and P0030 I was wondering if its still safe to drive the car around? I searched for it a little bit and was related to O2 sensor potentially cause by exhaust leak. I know it is more likely to be exhaust leak because I took my car to a place where the road was unexpectedly shitty but that was 2 month ago before the light came on.

Thanks for helping!!

Hi, no I only have a catback exhaust. I don't think my exhaust had a leak. How would you be able to tell? The dealers basically didn't do anything because of my aftermarket I have P0030 as well. I scraped my end of the down pipe pretty hard couple month ago. But it seems fine? It's the part where the muffler connect to the v clamp
