Stock 128i muffler inlet size?

KwlAznKid · 04-05-2018, 03:53 PM

Based on all my searching here I've heard the muffler inlet for a 128i is either 2.25inches or 50mm which is less than 2 inches, can anyone confirm the size for me? Thanks

I just pulled off my stock muffler. I'll try to get a measurement for you tonight after work unless someone beats me to it...

My Supersprint (made in Italy) resonator delete included an adapter sleeve, 2.25 " if using the stock muffler.
