The BimmerTrend N54 Stage 2 Bundle lets you build a complete bolt-on power system for your exact drivetrain and goals, all from one page, one checkout, and one fully compatible package.

No guessing.

No wasting money on parts that don’t work together.

Just real N54 power.

What Is Stage 2 on the BMW N54?

Stage 2 removes the biggest factory restrictions holding your twin turbos back.

With the proper bolt-ons and tuning, most N54 cars gain:

• +100–140 wheel horsepower

• +120–200 lb-ft of torque

• Faster turbo spool

• Huge midrange

• Much harder top-end pull

This bundle supports:

• Pump gas

• Ethanol blends

• Street & track builds

What’s Included in the BimmerTrend N54 Stage 2 Bundle

Every Stage 2 N54 build starts with a high-flow downpipe — this is what lets the turbos breathe.

From there, you can add:

Everything is selected to handle higher boost and aggressive tuning reliably.

Downpipe Options

Choose the correct version for your drivetrain:

Catless (RWD)

• Fits rear-wheel-drive N54 cars

• Maximum turbo spool and horsepower

Catless (xDrive)

• Designed for AWD chassis

• Same power gains, perfect fitment

Both options dramatically improve turbo response and top-end power.

Charge Pipe Options

The N54 factory chargepipe is weak and will crack under boost.

Choose the style that matches your diverter valve setup:

• OEM DV

• Tial / Turbosmart Flange

• HKS Flange

• No Charge Pipe (if already upgraded)

Upgraded chargepipes are mandatory for tuned N54s.

Intercooler Options

More boost creates more heat — intercoolers keep your power consistent.

Intake Options

Dual Cone Intakes

• Classic N54 sound

• Loud turbo spool

• Best airflow per dollar

Relocated Silicone Inlets

• Moves filters away from engine heat

• More consistent airflow

• Custom engine bay look

Tuning Options

The N54 bundle supports:

• MHD

MHD provides:

• Stage 2 maps

• Ethanol blends

• Burble control

• Boost control

• Live data logging

This bundle is designed to support high-boost twin-turbo tuning safely.

Why Buy This as a Bundle?

Most N54 owners waste money buying:

• The wrong downpipes

• The wrong chargepipe flange

• An intercooler that doesn’t fit

• Incompatible parts

This bundle eliminates all of that.

With BimmerTrend:

• Everything is matched

• Everything supports Stage 2

• One checkout

• One shipment

• One support team

This is the easiest way to build a fast N54.
