BMW B58 PERFORMANCE PACK

Take your BMW B58 to the next level with a complete performance package combining upgraded intake and exhaust hardware, ECU calibration, professional installation and dyno testing. Rather than treating each modification separately, the B58 Performance Pack brings the key upgrades together as one complete setup, installed and calibrated by the Paramount Performance team.

EXPECTED PERFORMANCE

Depending on your BMW model, the complete package is expected to deliver approximately: Up to 450 bhp and Up to 650 Nm

Performance figures are indicative and can vary according to the individual vehicle, fuel, condition and specification.

WHAT’S INCLUDED?

Performance Intake

A Ramair Performance Intake with Carbon Lid replaces the factory intake arrangement with enlarged performance pipework and a pleated performance filter. As well as supporting improved airflow, the system brings considerably more of the B58’s induction and turbo sound into the driving experience.

Performance Catalyst / Downpipe

An upgraded performance catalyst and downpipe improves exhaust flow and forms an important part of the hardware package.

M140i and 440i: Milltek 300 Cell HJS Performance Catalyst / Downpipe

M240i: Milltek Large-Bore Downpipe with 200 CPSI Performance Catalyst

Compatibility and suitability will be confirmed for the individual vehicle before installation.

Performance Cat-Back Exhaust

The upgraded cat-back system gives the B58 a deeper, more purposeful exhaust character while improving the complete exhaust setup.

M140i and M240i: Milltek Non-Resonated Cat-Back Exhaust

440i: Supersprint Stainless-Steel Cat-Back Exhaust

Exact specification may vary according to model year and vehicle configuration.

Paramount Performance ECU Calibration

Once the performance hardware is installed, the ECU is calibrated around the upgraded setup.

Expected output is approximately 450 bhp and 650 Nm, delivering a substantial increase in power and, particularly, mid-range torque.

Professional Installation

All components are professionally installed at Paramount Performance by our experienced workshop team.

Dyno Testing

Following installation and calibration, the completed vehicle is tested on our in-house rolling road so its performance can be assessed.

WHAT WILL IT FEEL LIKE?

The biggest difference is the additional torque. With expected gains of between 150 Nm and 200 Nm, depending on the model, the B58 becomes considerably stronger through the mid-range, giving the car much greater urgency when accelerating and overtaking. There is also considerably more character. The Ramair intake makes more of the engine’s induction and turbo sound audible, while the upgraded exhaust provides a deeper and more sporting exhaust note. The result is a more powerful, responsive and involving version of the B58, with the hardware and ECU calibration developed as one complete package.

ONE PACKAGE. ONE WORKSHOP. ONE TEAM.

Performance and fitment information

Performance figures are indicative expected outputs for a healthy vehicle fitted with the complete specified package and running suitable fuel. Actual power and torque can vary according to fuel quality, vehicle condition, transmission, existing modifications, environmental conditions and individual vehicle specification. Vehicle equipment varies according to model year and production specification. Component compatibility will be checked against the individual vehicle before installation. Some performance exhaust and catalyst components may be intended for motorsport or competition use and may not be suitable for use on public roads. Our team will advise on specification and suitability before the package is confirmed.
