Great and more durable upgrade

Got a hole in my stock heat exchanger so this one having a rock guard is a huge plus. Holds more fluid too so this is a nice upgrade.

Turbo Install Kit (B58/B58TU)

Never received order

Been over a month, have not received my order and according to UPS they never received it although MRM says I received it 21 days ago. Will be reporting the fraud with Visa.

Great product 2 months later

Car feels more solid now. I'm surprise it made this much of a difference and of course my noise is gone. Installation was easy and I was well crippled at the time. Wish I had a Sawzall at the time of install

Excellent

Best thing anybody can do to their n63tu2

Not buying from you again.

So I bought the wrong part and I asked for returns for about a week giving numerous calls about the return policy and how I can send this back and get my money back. Never got a proper response so I won’t be ordering from you again and wasted my money.

Very late and lackluster customer service

Vendor cancelled my first order, and for the second order did not ship my TU pump until I submitted a lost item order. I waited about 15 days altogether.

Got the Job Done

Had a diaphragm failure but was prepared with a kit from MRM, got me back on the road in 5 minutes. Can't speak for longevity but it sure did save my butt!

Check engine

Check engine doesn’t turn off when I flash your tune

Hello,

If you are getting a CEL due to having catless downpipes, then you did not select the option for disabling the Catalytic Monitors in the flash options. If you don't select 'OFF' on this it will continue to throw a CEL (See here: https://i.imgur.com/JlKn5cy.png). If you've already done this then you have another issue and need to read codes and see what is causing the CEL. BM3 doesn't disable CEL for anything else.

Feel free to email us or Bootmod support if you have additional questions. Hopefully you'll consider updating your review after this.

MRM Support: Sales@MRMPerformance.com
Bootmod3 Support: support@protuningfreaks.com

UPDATE: As suspected, customer is getting a CEL due to having bad O2 sensors; not for having catless downpipes. For obvious reasons, BM3 does not remove CEL for damaged O2 sensors as it would be a massive issue not knowing when your O2 sensors go bad.

Just love the MST air intake, have it on a 2018 b48 330e. The sound is amazing and it just make me smile driving.

Honestly I’m disappointed I order my tune 16 days ago and I’m still waiting for the cable to actually be able to tune my car

Amazing!

Completely satisfied with my purchase. It was a 5 minute setup with registration and flash. My biggest thank you to the wonderful support and team over at MRM, to help start my B58 540i build!

MRM Performance Decals
Antonetta Tsakonas (Brooklyn, US)
Excellent

Really like the colors

Excellent

Perfect fit really quality so happy

Good drive shaft and shipped at a good amount of time

I would like to if there were better instructions on how to install it, and adjust it, when replacing also recommend replacing the flex play as my vehicle started to vibrate after installation

Loved this catless downpope!

Just make sure to buy a new gasket that goes in the slot on the downpipe where it connects to the turbo! Looking to get fueling mods soon!
