Issues regarding Exhuast and downpipes
Hey guys,
I have a 2021 BMW M340i fully stock. I’m getting a Titanium Cat-back exhaust along with cat-less downpipes…. My only concern is that since im keeping my car fully stock and not tuning it, will there be ANY sort of mechanical issues i could run into with the cat-less downpipes? (i already know my engine light will come on but im concerned about any other issues with catless downpipes) (Ps: I also drive daily almost 80 miles a day for work so take that into factor too ….. all highway) |

I went catted on my choice of aftermarket downpipes, however if I didn’t care about the check engine light and losing remote start, I would have gone catless all the way.

No issues except for emissions. What is the brand of your exhaust?
