Yup same downpipes
you should swing by a shop and see if it was installed correctly since its not a 100% direct fit, you might have a small leak.
I had mine installed at bmw and they did a fantastic job as well as ordering additional gaskets, bolts to make it all work.

Here is a video of muffler delete with FI downpipes while getting my X pipe done

I'll try to get some this week, this car is raspy as hell after the downpipes, resonator delete and having the exhaust actuators open. need to get that sorted out tomorrow.
Thanks my friend, looking forward to seeing them. I haven't been able to get many break in miles on mine, should be ordering my Jb4 very soon.
3rd and 4th gear pull
Look under gear column to see which is which
Jb4 stage 2, FI 200 cell downpipes, X pipe and exhaust actuators back on

Hey guys,

I just bought a x5 m50i in Australia and was really hoping if you could help me choose which route to take with the exhaust. I don't want any drone and want to be able to maintain the ability to 'quieten' down the sound.

Would a resonator delete with an x-pipe or h-pipe be the way to go?

Does anyone know where the OPF is on these cars? Might be worth doing an OPF delete to see if it increases more sound?

I am about to embark on this with an exhaust group in Melbourne next week, a simple resonator delete with a straight pipe, it's being done monday. I'll let you know my thoughts.

Please do! I was speaking to a person from a reputed exhaust shop in Sydney and he mentioned that a resonator delete will only yield about 3-8% in terms of volume and won't make the car 'louder' like I want it but might introduce drone.

He recommended I keep the factory valves and he'll set up a unique quad muffler design that allows for a 20-30% noise reduction when the valves are closed and will be equivalent to a muffler delete when open. He quoted roughly $1-1.2k (AUD) for that job

I recently did a resonator delete (x pipe) on my X5MC. It did add some extra grunt on Cold Start and some burble in Sport/Sport Plus. TBH, not much of an improvement in overall sound. I do hear more exhaust note in the mid range, and more rasp when revving, but absolutely no drone.

I'm sure the X5MC exhaust note is more aggressive out of the box than the M50 but I didn't find this to make that much of a difference. your miles may vary.

I may consider coupling with a secondary CAT delete or a new muffler (when available Dinan/Remus). I think with the N63/S63 engines, you really need downpipes to get the proper sound. otherwise these motors are fairly quiet in there operation.

I believe its a flowmaster. my local performance muffler shop installed it and had it in stock

Thanks
I got my resonator delete done at joeys diagnostics on Hylan Blvd in Staten Island, paid around 200-250
They are a specialty muffler shop so i'm sure you can find cheaper if you wanted
Did they use stainless steel pipes or regular pipes and was the weld job clean or messy let me know thanks

Resonator delete is enough, if your in Sydney, i highly recommend Lamros Kouriefs from HiTech Mufflers in Sydney.

The resonator delete makes a huge difference.

Did they drop the whole exhaust down to weld the top portion so there won't be any leaks

Do the Australian delivered M50i's have OPF or not? I know the M2c deliveries followed US spec and didn't have them, not sure about the X5s?

What is OPF? Same as GPF? I guess I am the only person here who does not know 150 of these damn acronyms.

I believe the OPF is the same as what you're calling a GPF @[speedyman]

On a side note, I had a Catback system installed on my X5 with a H pipe. I have 2 mufflers (1 into 2) on each side and kept the factory valves. I'm currently experiencing horrible drone between 1100-1600 rpm with even partial throttle applications.

Also, I personally feel like the valves aren't doing much at all - I can't feel any airflow changes between sport and comfort by putting my hand next to the tail pipe.

Does anyone know what might help reduce that drone down? It's difficult to drive the car now

Also - the exhaust isn't that loud even with the new system if anyone was interested. My X3 M40i (2019) had a louder cold start.

What is the diameter of the stock exhaust there? I am going to do this and debating x pipe or straight. Thanks!

Well.. the H pipes have been proven to be pretty quite in terms of volume according to Ninefourteener. I think what you should have gone for is the x pipe set up with the exhaust valve permanently open.
