If you own an S58-powered BMW, this is the fastest, safest, and most cost-effective way to unlock Stage 2 power in one shot.

The BimmerTrend S58 Stage 2 Bundle lets you build a custom-tailored power package by selecting the exact parts your car and goals need — all in one checkout, all guaranteed to work together.

Instead of piecing parts together from 5 different vendors, this bundle gives you a single optimized upgrade path:

• ✔️ Proven S58 downpipes

• ✔️ High-flow intake systems

• ✔️ Performance midpipes

• ✔️ Optional BM3 or MHD tuning

Every option in this bundle is track-tested, street-proven, and daily-drivable.

What Is Stage 2 on the BMW S58?

Stage 2 is the point where your S58 truly wakes up.

With the factory downpipes replaced and airflow increased, your turbos can finally breathe — allowing tuning software to safely increase boost, torque, and throttle response.

Typical Stage 2 gains:

• +120–180 wheel horsepower

• +150–220 lb-ft of torque

• Faster spool

• Louder turbo & exhaust tone

• Much harder pulls above 4,000 RPM

This bundle is designed to support BM3 & MHD Stage 2+ maps, ethanol blends (E30–E50), and high-boost setups.

What’s Included in the BimmerTrend Stage 2 Bundle

At minimum, this package includes a high-flow S58 downpipe — because a downpipe is required for Stage 2 tuning.

From there, you can add any combination of:

This is why we call it “Build-Your-Own” — you only pay for what you want, but everything works together.

Downpipe Options (Required)

Your downpipe choice controls power, sound, emissions behavior, and smell.

Standard Catless Downpipe

• Maximum horsepower

• Loudest turbo & exhaust sound

• Strong exhaust smell

• Best for track or aggressive street builds

XL 3.5” Catless Downpipe

• Highest possible flow

• Best for big-boost, ethanol, or hybrid turbo builds

• Supports 700–800+ WHP setups

• The choice for serious performance builds

Ceramic Heat Coating (Optional)

Adds thermal protection to keep:

• Engine bay temps lower

• Intake air cooler

• Turbos running more efficiently

Highly recommended for high-boost Stage 2+ cars.

Intake Options

Your intake affects sound, throttle response, and turbo efficiency.

Standard w/ Heat Shield

• Best value

• Clean OEM+ look

Silicone Front Mount Intake

• Maximum airflow

Midpipe Options

Midpipes affect sound and volume, not horsepower.

If you’re running a catless downpipe, most owners choose 3.5” for daily driving or 4” for full race sound.
