- Metal Zip-Ties: amzn.to/2ZOxS86
I decided to slightly modify the stock exhaust of my BMW 550i F10 with the N63 engine to see if zip ties are a solution to a louder and better sounding exhaust. This mod is pretty much free as all you need is two metal zip-ties with which you will keep open the exhaust valves and thus increasing the sound and flow of the stock exhaust. This should work the same on any BMW with the N63 engine such as 550i, 650, 750 and the X5 and X6.

It's easier to just bypass the vacuum line. The vacuum pump is located behind the paneling on the left side of the trunk. Pull off the hoses from the inlet/outlet and splice them together with a coupler. Takes about 5 minutes total and is so much easier (and cleaner) than forcing the calves open and strapping them into position
I like the look of those metal cable ties
I think I'll have to buy some. Can't have too many fasteners in the garage!
Since I moved to a house I have been collecting more and more screws, bolts, and everything else I find useful. It’s an addiction.
Thank you for your videos Simple Car Guy, they have been helpful especially the one that taught me how to change my spark plugs, with your help and guidance and only took about 1 hour and was a fraction of the cost versus the dealership.
I have a 2016 550i n63tu, and really want to do this but will it potentially cause any damage to keep the valves open all the time?
I've glad my video helped you change the spark plugs!
As far as the risk on keeping these open, it is up to you. From what I have read and understand of these cars, it is there to make the car quieter on cold starts as this is a luxury car and not a sports car. It may also reduce the back pressure (a TINNYYY bit) and use a very small amount of fuel more on start up sequence.
I like your solution not like bimmerlink 39 euro
Hey bro I like your vids i recently bought a 2013 bmw 550i from CarMax great maintenance and well taken care of I also bought a warranty up to 125k miles to cover major repairs in case something goes wrong. How is the car reliability I plan on doing proper maintenance as well.
I have a video on issues to expect from these cars. Normally I recommend 2014+ for the 550 as they have fixed a lot of issues from 2013 and earlier cars, but since you got the warranty, you should be good to go! Change your oil every 5k miles!

SimpleCarGuy nice I couldn’t find any 2014 models with low miles so I got the 2013 model it has 50 less hp but 400 is plenty for me with the 450 lb torque it’s awesome I’ll check it out.
@@yearight1800 You won't feel much of a difference, I drove my buddy's 2012 550 before I bought mine and the difference is not very noticeable. Congrats on the car!
Timing chain at 72,000 for me, when you hear it whine dump ASAP (2011).
Ivan O you made a big mistake going for a 2013 instead of a 2014+ with N63TU. Can’t stand when people buy first then ask stupid question later. Good luck, that engine literally sucks
Great video thank u
Is it safe to do that? I'm buying same BMW 550i xdrive 2016 year model the last body shape
I still need to do mine on the E89 but its stuck and i don't want to damage the vacuum line. I might get a heat gun on it and see if that helps release it. I don't want to damage the line because i quite like the sound that the valve makes when it opens and closes when i floor it so want to be able put it back on if i don't like it off😊
I used a screwdriver and just gently pushed it off with the help of WD-40. Didn't take much effort at all. I plug it back in from time to time just so that I get different sound.
SimpleCarGuy thanks for the tip. I’m going to give it another go at the weekend👍
Hi,
Have you noticed any loss of torque with this mod?
Best regards,
Sven
Hi Sven,
Not at all. These flaps normally get opened automatically once the car is warmed up. They more or less serve to reduce the noise on early morning cold starts since it's a luxury car and not a sports car. Thanks for watching!
Thank you for the fast answer, I'm definitely gonna try it then. :)

Hi I have 535xi with 110k .. any things I have to consider for this mileage? What’s the reputation of this engine after 100k?
As long as it's not an early 2011 car and it has been well taken care of, you should be good to go. The n55 engine is probably the best engine that came on this car, so make sure the engine wasn't overheated, no coolant or bad oil leaks. After 100k you can expect to change HPFP, Water Pump and injectors at some point. I'm not aware of other major issues.
SimpleCarGuy Thank you for reply.. you said early 2011 so I have to look at the manufacturer tag to see which half of 2011 been made? Also what’s is HPP.. No overheat nor leakage .. I am use Castro’s full synthetic high mileage do you recommend other brand/spec?
I meant early car in the model years, so pretty much the 2011 model year. They aren't necessary a bad car, but it's the first year for the engine so there were some issues they resolved in 2012. HPFP is high pressure fuel pump, common failure on these.
SimpleCarGuy 🙂
smile6868 The 2011-2013 have the most problems that’s the n63 engine the 2014-2016 and much more reliable they first most of the problems from the early years they have the updated n63tu engine.
Does that affect fuel consumption?
I theory itll get a very small bit better. In reality no.
Just get a muffler delete Cheap at your muffler shop it's drone at 2rpm but you actual performance u can get resonators remove as well to get rid off the drone one muffler deleted
I would t recommend that at all. I bought a 335 with no mufflers and it sounded ok at start up, but was horrible on the highway. Lots and lots of drone, very unpleasant to be in.
does it work on s63 engine
I’m not sure how the exhaust is set up on the s63. I believe M spec models allow you to open or close the valve via buttons inside the car.
Can you do this on a 545i
What year 545i?
@@SimpleCarGuy 05
I don’t know for sure, but I believe on yours there is a vacuum line that you can pull off and put a gold tee into. It’ll stay open permanently then. Look up golf tee trick
@@SimpleCarGuy okay so don’t try to unplug the valve like other models I lost torque when I unplugged it still same power but not much snatch so I hooked it back up ... also it didn’t push any airflow out of the right muffler so I assumed it doesn’t work for me
This is no good when having downpipes on cold start
what engine is the 2011 bmw 550i
That's be the N63 engine (not TU, big different there).
@@SimpleCarGuy ohhhh ok thank my friend bought a bmw and he wants me to help him with little mods and i’m not a big bmw guy so thank you
@@SimpleCarGuy do you know any cheap mods i could do to a 2011 550i
@@user-cs8dk5mn7v What mods are you looking for? Performance or visual? I wouldn't recommend doing any performance mods on the 2011 engine as they aren't the most reliable to start with.
@@SimpleCarGuy more visual mods
