540i Exhaust tips
I got a 17 540i M sport wanted to do a muffler delete and change the tips to a M5 dual tips but didn’t know if I needed to change the rear diffuser or it would fit perfect. Any recommendations I would appreciate it!

I think you need another diffuser

Yeah, with a quad exhaust, you may not have to change the diffuser, but you will want to. It won’t look good with the stock sport diffuser, assuming you have a sport. It you don’t you have to change the bumper.

As I mentioned, there are only a few diffusers that will fit 4” quad tips. This was one of them. I’m not usually an eBay shoppers for car stuff, so I went into this thinking it’s cheap enough to be disposable if I didn’t like it or it didn’t last or the quality and fit was poor. Going on two years and I love it.

This. Quad tips won’t work with the OEM 540i MSport diffuser. I had a Remus exhaust with 102mm quad tips that required the M550i OEM diffuser (or aftermarket, but I chose OEM). Still have the Remus exhaust but went back to original 540i exhaust and diffuser.

Is there a reason why you reverted to the original exhaust?

I liked the sound but my main passenger did not. And I plan to have both car and main passenger for a while so something had to give. And since she likes my G30 better than the G60 she saw in the Walken SB commercial, I may keep the car even longer. TBH, I love my G30 so that’s not a sacrifice.

I’ve heard of drone noises from the cabin , would there be any noise if I do a muffler delete? Cars too quiet in stock can’t keep it like that |

Sorry, no idea. I just swapped the OEM axle back exhaust for the aftermarket one. I’m sure there are posts by people who have done that.

The M850 has a better sound from the factory and I think it’s because it only has one resonator whereas the M550 has two.

What are you going to do with the exhaust now? That’s the one I wanted to try but I’m scared with a downpipe it is going to absolutely scream for a daily driver.

Drone is annoying with a muffler delete, i drove a friends one and it was noticeable extra drone, even over my sports cat with Remus axle back setup. it would drive me mad on a long journey

I am with you. In addition to the massive drone produced by a muffler delete, the car just becomes as annoying as hell. Some people can't discern between a car sounding tastefully louder and sounding like a shit riced out Honda.

Back to OEM setup and keeping it this way. It’s factory quiet but that’s fine.
