so- had the exhaust checked out by onyx

they say the exhaust is great and theres no issue with the midpipe itself-

the only cause for vibration could be this connection here- its too rigid and high up.

theyve said theyre happy to cut it out for me but i should speak to swift first see their thoughts

overkill also replied they can fab a resonated exhaust as oem wont match up to remus catback for 799

Im thinking- cut this section out see how that affects things hopefully thats the vibration and drone sorted

otherwise I can go for the overkill midpipe- i think remus is great when i want to be loud but most of the time its just too loud

but then im left with the remus midpipe and itll probably take ages to sell

posted my vibration issue on the exhaust area hopefully somone has an idea of what to do

in the meantime car is currently getting front cermaic tints

and im booked into onyx for a osprey/bosch high pressure fuel pump and installation of the steering wheel trim

[NotBobby]

Whilst the cars in at onyx considerig getting a new diffuser- hate the standard 550i one I had to get becuase of the remus exhaust, it just looks so meh


Juggling between these 2


v style looks so much better imo but its also more than double the price, thinking should I hold off for a bit?

But then again cosmetically the builds nearly done, im ripping off the yellow pinstripe and sticking on either black or dark grey

I appreciate you taking off the yellow pinstripes, it looked almost cartoony to me. As for the diffusers, I like the first one with the thinner 'diffuser' fins. The second one also has that bottom piece under the tailpipes that makes it look too bulky to me.

Yup really nice guy and great work, he did give me an estimate but after tax it might have just been cheaper to get a replacement off ebay hahaha

Pinstripes came out much worse than I imagined haha, this is the m4 I saw at a show that looked great (not sure of forum rules regarding posting other cars i can delete the picture if needed)

Just stuck between black or grey- when the yellow was pulled off the spoiler it did peel off the lacquer

With the diffuser i agree regarding the section below the tailpipes but reflector the side looks significantly better than the top imo, also the boxier look appeals to me, I've attached how much diffuser used to look

They told me at the time it hit 450 on one run but I can't see that on the graph unless im reading it wrong

Mate what mods are exactly done to get 440hp? Why do you let's say didn't get MHD software with all the licenses but went somewhere to do tune by someone? What were your reasons? Thanks, buddy!

Hey so- I've never modded a car before so i was a bit apprehensive to start- the first tune was simply bm3 stage 1 and xhp stage 2

Since then I've had a fair few mods but some probably have negligible impact but ill list everything here

Bm3 stage 2
Xhp stage 2
Sports cat
Vrsf charge pipe
Mst air intake
Ngk 92401 spark plugs
Remus catback with non res midpipes
Also full carbon body kit but this wouldnt affect the hp and probs made aero worse if anything hahaha

[carssense]

Haha, mate you're wrong carbon fibre increases a visual vibe of speed and flair points! Definitely adds up like 20-30hp,

Thanks for your response I am still sorting mechanical issue because I bought car after small NSF damage and decided to do it all on my own as a challenge!

Wish me luck! 😂

Yup the carbon goes zooooom haha, how deeps the damage? Been wanting to do work on my car for a while but been lacking confidence, for me doing stage 2 map myself was a big step

[NotBobby]

Took the car to jc customs a few days ago- had a resonator put in and had him rejig both mount points- vibration has decreased overall a bit and now somehow most prominent between 1400-1900 rpm- how this work has focused the vibration makes no sense but ill take it for now


But vibration and drone still present going back soon to show him with a test drive the exact issue- planned to do this first visit but had to rush back to work

[NotBobby]

Dropped the car off today at onyx for osprey/bosch tu high pressure fuel pump, carbon steering wheel trim and oil service

On another note anyone had issues with the bm3 obd adapter? Mines been rubbish since I got it always taking several tries to connect constant on/off

Never had this issue with obdlink cx so I know the obd port on the car is fine

Looking into a wired enet connecter

[NotBobby]

New carbon fibre steering wheel trim- looks good but the fitments not super flush

Oh well cant have everything

It has definitely added at least +40bhp

[NotBobby]

Some thoughts-

Resonator has reduced overall noise but

Cars felt a bit sluggish since Ive had it- been rainy though the past few days and heavy traffic everywhere today though I've had the chance to push a bit

And yes it feels much slower, also revved the car a bit and it just sounds muffled

This plus the vibration still being present means I have the worst of all worlds

Kind of at my wits end- going to speak to james at jccustoms again soon but really need a resolution. Honestly might just go back to oem

[NotBobby]

Alongside the steering wheel trim- got engine oil serviced and had the osprey tu high pressure fuel pump put in

Got this annoying message now however - driver assistance restricted

Guessing its just a faulty sensor

- not done any 0-60 pulls but with the issues mentioned in the previous post regarding the resonator- car just really feels sluggish

Also updated to stage 2+ bm3 map

These are the setting I have for burbles, it was originally much lower but turned it up as I couldn't hear post resonator but even at such high aggresion its barely there 🫠

Nice to see another detailed build thread coming through!

Thanks for the mention and shoutout

Build is coming along nicely... you should of gone stage2+ from the start as would of been cheaper buying the maps, but I guess going through the stages you can see and feel the differences.

Colour looks really good! Something unique

Im terms of exhaust issues, so you have had a resonator fitted to the Remus Midpipe or back on the OEM midpipe?

I had some vibration issues where the Remus midpipe was touching the cross member brace. I fitted the thicker F90 M5 one and it was touching slightly. I was able to solve this buy twisting the mipe pipe away from the brace, but then also wrapping some exhaust wrap tape from Funk. The vibration issues for me have gone now.

Look forward to seeing what's to come in the future on this car

Bmw said sod off essentially ,in a nice way, you havent mentioned that before.

Which to be fair I didnt care about the scuffing but I did care when it got worse, one of the sales team at bmw gave me the number for 'jim the trim' honestly great guy too, was a hassle getting ahold of him but thats simply due to how busy he is- he checked it out on a friday but I was going to show on Saturday so he drove back down monday and had it back to me by Thursday

Hi, I just saw this post and I have the exact same issue, on the exact same headrest ... at the passenger. Did you order a new one, did you find a way to repair it/fix it? Thanks a lot for your answer!

Hey
Thanks

Yup would have been a bit cheaper but fun in a way to go through the stages slowly see the difference each mod brings

Resonaters currently on the remus midpipe- ill have a word with jccustoms regarding as hopefully its a simple as doing that because

So post the work done by him vibration has become a narrower band from around 1400- 1900 rpm, how the logic on that works I have no clue

Resonator has decreased normal drone too but- when I rev it it just sounds so muted now- like worse than when it was oem +sports cat

Got a few things planned I haven't see you do yet so hopefully the builds should diverge a bit more haha but really enjoying the journey so far- minus the vibration issue

Hey yes-

Got it ‘repaired’ by jim https://www.instagram.com/cornish_jamie?igsh=eTh0YWlhOTEzOXU2

He basically took the whole headrest off and added a new section of leather so it looks like new however it may just be cheaper to look on ebay for a new headrest

Nice build thread, car is coming along nicely.

Sorry to hear about your vibration issues, I know how frustrating things like that can be!

Have you thought about refitting the OEM exhaust to see if the vibration disappears? If it does then you definitely know it’s your new exhaust, if not then it could pinpoint it somewhere else.

As I said in your other thread I don’t have any vibration from my Remus exhaust, I would think with a brand like Remus you are paying for a quality product so it shouldn’t vibrate.

Can you advise what issue you had with the downpipe fitment? You said your car only had one sensor? Did you have to order another sensor?

Also did you eventually get the BM3 oil light issue sorted ?

Thank you!



So its definitely remus as prior I had the oem + sports cat and that had 0 vibration. And i agree- one of the reasons I didn't go for a custom exhaust was the trust with a brand like remus+ plus other glowing reviews here, they also haven’t responded to my emails, so super disappointing on that front

With the one sensor it was a case of needing to get a new compliant sports cat in but I'm not sure of the exact specifics here to be honest but had no issues as far as Im aware i still have only one sensor.

Bootmode/pro tuning freaks were actually very quick to respond on Friday, car just in with bmw heathrow for the recurring sunroof issue but Im pretty sure bmw will send me a different map which ill just need to flash
