Hi there,

I have a bmw 230i with the B48 engine

Does anyone know the diameter of the stock downpipe? (the side that connects to the front pipe)

Or the diameter of the stock front pipe?

Because i want to change the downpipe and without these two diameter i can't pick anything aftermarket...

You dont need to know the size unless you are building your own downpipe. The offered downpipes come with the correct connection size or else they would not fit.

We offer Active Autowerke, Evolution Racewerks & Armytrix downpipes that fit your car

I bought the car with a custom exhaust on (stock downpipe) but i don't like it and i want to change all the exhaust line. In order to do that i need to know the internal diameter of the stock front pipe or the external diameter of the stock downpipe
