Anyone had a muffler delete on 50i?

Highway video... I will post up the acceleration and cold start videos within the next few days. It was extremely windy today and my runflats need replacement. I will take another video after I install my new wheels and tires in a few days.

If we were to find a local exhaust shop and instruct them on this, could you provide exactly what your shop did? I might go with quad tips.

How is it during cold start? My 335i would be really loud an shake the neighbors house. Any issues for you?

Thank you very much! I just had the exhaust deleted and added an x-pipe. Nothing was removed except for the mufflers. The x-pipe was added to bring the sound back together.

Cold starts aren't too bad. It's a little loud but not overbearing. I will get a video.

P.S. I'm wondering if I go with downpipes - that may become too loud eh?

The resonators are still there as far as I know. I have been working non stop and haven't had a chance to play around too much. I should be able to verify by tomorrow though.

I will verify but It should be stock resonators into the x-pipe then extended piping to replace the mufflers mated to the stock tips.

I would be very very appreciative if a cold start video if you get the chance.

Great job!

Haha.. you really can't beat it for the price!! I am absolutely happy with it.

I will post up a cold start video sometime in the next few days. Everyone loves it so far!!

This sounds really good! Thanks for taking all the videos!

For the x-pipe, did the shop make it or use a generic x-pipe?

Would really appreciate that as I think the rest of us would as well. You are doing solid work here for the community. Id go over to my shop today and get this done.

With flashing becoming a reality soon, one could simply opt for a cold start delete so this doesnt wake up the neighborhood when you are getting ready for work.

It was just a generic x-pipe (non resolnated).

Really happy I can help. .. I can't wait for more tuning options. I have the BMS Stage 1 but I would love to have a real tune.

Very true on the cold start delete I have that option checked on my Evolve tuned M6 .

Ah I see! That explains no drone at cruising speeds
Resonators are the one responsible to cancel those annoying drone waves at around 1800-2300 rpms

One question tho: is it X-pipe or H-pipe?

[Maverik259]

X pipe

I know it's hard to objectively say, but how much louder exhaust is now roughly in your opinion? Like 20% or more like 50% louder?
One more question - judging from your wife's departure video - at idle and low speeds - exhaust is SO GOOD, but I'm just wondering how it sounds at full throttle - any abnormal sounds rattling there? Just want to cover all bases before jumping into it

P.S. was deleted muffler heavy? For me any weight loss is a good thing (I have rear seats removed lol)

[Maverik259]

For $300 I will look for a shop to do this next weekend lol

I would say about 50% louder.

I still need to get acceleration videos and I will try to get it done before the weekend.

The muffler was definitely heavy. I would say its around 60-70 lbs or so.

Unfortunately, I have kids and actually need my back seat. haha..

Cold start in the garage then RPM drop after warmup from drivers seat with door open.

Thank you!!! And ... DAMN! That's just about perfect!

Thank you for showing us the way!!!

mdemon Dude, where is your shop? Can you guys do something like this???

Thanks!!

[DuSh]

So I guess something like this will do? https://www.summitracing.com/parts/j...SABEgJLHPD_BwE

Another thing is that it turns out rear muffler is attached by clamps only - so it's possible to just unclamp and take whole part out and store it for when you'll need to revert it back

But in that case will need some extended pipes and tips. I'm thinking we can even go with double tips if we want to, like any type that will fit in the opening in the bumper - could be black tips or blue color ones and I guess any shape if it fits nicely

TheLastDetailNV please do the drive by with full throttle (or close to it) when you'll have time - we would really appreciate that! That's the only thing left to film and I'm ready to go to muffler shop

Stop procrastinating and go do it already! I doubt the drive by video would change your mind!

Besides, it is pretty inexpensive and completely reversible if you end up hating it.

I just need to find the time!!!

My pleasure! 😀👊👊 Plus there is the option to add mufflers or resonators to reduce the sound if desired. There is a lot of room to make it individualized.
