Mods to hear your turbos better on b58

340cheese · 08-28-2018, 05:50 PM

Hello everyone,
What are some modifications I can do that will let me hear my turbos better on my 340i. Please leave your suggestions below. Thanks!

What up...Depends on exactly what you want...I just got the Agency Power air intake for my 2019 BMW 440i with the B58 engine and it sounds way better than stock (also looks better). If you are looking for the loud whooosh then you should look into a turbo blow off valve

open element intake - bms as an example

Catless/high flow catted downpipe, intake, and/or bigger turbo.

Your car only has one turbo. Intake will make more noise.

Ive taken the sound deadening out of the engine bay, and have a K&N filter. No difference at all lol.

BOV of B58 is electronic，no way for mod.

No. Keep the hood and mount one in each kidney grille opening.

This. Here is a video I made when I first installed my Agency Power intake, this was the only "performance" modification on my car. This is about as close as you can get without having to do a downpipe or a tune that turns the boost up.

First, an intake like many stated already. But I wanted more. So I did the intake silencer delete with custom intake parts and the difference was night and day. Now I hear the turbo spool in the car while driving just as much as if I was in front of the open hood before that mod.

Well worth the 100ish cost in parts.

estorilbluef36 · 08-30-2018, 11:47 AM

catless downpipe

FWIW - The Agency Power intake removes the factory noise suppression. BMS does not.

catless dp and bms intake. I have the AFe momentum gt and don't hear the turbo anymore.

dime4dice · 10-13-2018, 07:38 AM

I recently installed the ds1 catted downpipe with the bms intake, sounds very good. Then again I also have the Dinan midpipe and exhaust.
