Cant wait for the catless dps to get in, then stage 2 and Im done. From what Ive read is that the oem tips are spot welded on. Dont see why a muffler shop couldnt remove them and put on whatever tips you want as long as they fit the diffuser.

I really wanted those double round tips. I think it pretty difficult to cut the tips off the stock exhaust and spot weld new ones in. I've only seen one person do it and they stuck out too far IMO. My diffuser will fit the Dinan tips. I made sure of that before choosing it. After this is done, I'm sure I'll want to know more about down pipes. You can take me to school.

I've also heard that cooler plugs are preferred for DPs, especially catless. You might want to look into that. |

I can't imagine it would get any power, but I know sometimes with exhaust modifications you can screw with the power band and you can lose low end and Dan top and or vice versa I'm just curious for those of you who have done a resonator delete by having a muffler shop, Weldon straight pipes did you notice any kind of change and how the car drove or does it drive exactly the same? ?

I recently did the res delete too and replaced with 3 inch straight pipes. Originally I wanted to do an X-pipe but the muffler shop told me they'd need to bend the exhaust brace in order to fit in 2.75 or 3 pipes so I went with straight pipes. The result is what everyone else says: no drones (big plus), no noticeable difference in comfort/eco and subtle increase in sound in sport mode. I haven't heard a drive-by sound yet but the car is so well isolated I couldn't really tell the differences inside the car. The major change would be the loud burbles.
On LCI/iDrive7 there's an option to change the engine sound which also controls the exhaust flap, so if I just want to drive fast without annoying anyone with the pops and bangs I can switch sound to "Reduced" or "Depending on drive mode". Setting to "Sporty" will give really loud cold start since the exhaust is fully open. This is really best of both worlds and best bang for buck exhaust mods. Stealth when you want to and flexible how you want the sound turn out to be. |

i took both resonators off its in sport plus, the engine sound is in sporty and it’s honestly not much difference just a bit more crackles , nothing really louder when driving , went back to shop had them put on a xpipe and still not much difference . i mean my m340i i spent 175 for a catless dp and my exhaust was perfect , this car doesnt really have a great v8 rumble , do i need to change the muffler? everyone seems happy with resonator delete. but i mean really on a 1-10 scale it went from a 2 stock up to maybe a 3 with delete even all my neighbors say its not a drastic change glad it was only 250 bucks and not alot more. i guess i was just expecting alot more sound i got a few more crackles and pops which i like but not more v8 sound and its really not any louder with or without xpipe

catted downpipes could be good for me, but even more expensive since they come as pairs on our engines.

I have the Dinan x pipe with stock muffler. It is more muted than just a resonator delete by comparing to online videos.
I would skip any X or H configuration Dyno comparison of stock center pipes with resonator versus Dinan X pipe (with stage 1 software) I gained 1 horsepower. You are gaining noise, not power. |

Note that the muffler is different on the 2020+ M550iX. The muffler is louder and apparently has less baffling than the 2018-2019. I have a remote valve controller too, and tend to run it open occaisionally. https://x-ph.com/cg-precision-vsc-2-...nd-controller/ |
