M550i Aftermarket tips?

michaelalex17 · 06-15-2025, 05:33 PM

Hello,

I just got a 2018 M550 and want to get quad tips installed. I realize it’s a bit of a tricky job but I have seen a few threads of people getting it done. I want tips that are around 3.2-3.5 diameter I don’t like giant 4 inch tips. What I don’t know is what the inlet size should be or tip length. If anyone has any info on this it would be greatly appreciated. Thanks!

your best bet my guy is to take it to your local muffler shop, they'll set you up.

I don’t want the muffler shop to give me random tips they have there that’s why I want to know the right dimensions of what to order
