Benefits of Upgrading with B46/B48 Downpipes

Upgrading your B46/B48 engine with performance downpipes offers several key benefits, like more power, more accurate throttle response, and professional quality sound from the engine.

Get More Power and Torque

By reducing exhaust backpressure, downpipes allow for a greater amount of flow of exhaust gases. Usually the gas is blocked and provides the least gain to horsepower. But a B46 downpipe can solve it and overclock the horsepower and torque. With a tune anyone can get 15-27whp.

Improved Throttle Response

The reduced restriction from the B46/48 high-flow downpipe ​results in quicker turbo spool-up times. It results in immediate power delivery and improved throttle response. So, it can help a driver control the car far better than the stock downpipe.

Enhanced Exhaust Note

Who doesn’t like the BMW engine sound? The Supra 2.0T & BMW V2 B46/B48 Racing Downpipes often produce a more sporty exhaust note to add value to the overall driving experience.

Why High-Flow and Catless Downpipes Matter?

B46/48 high-flow and catless downpipes are important for maximizing engine performance in turbocharged vehicles, especially those with the BMW & Supra B46/B48 engines.

●      High-Flow: Supra 2.0T & BMW V3 B46/B48 Racing Downpipes high-flow downpipes are designed with larger diameters and smoother bends to minimize restrictions in the exhaust system. So, the flow comes out more freely in order to improve turbocharger efficiency.  

●      Catless: On the contrary, Supra 2.0T & BMW V3 B46/B48 catless downpipes eliminate the catalytic converter, further reducing exhaust backpressure and allowing for increased airflow. It is the key to significant gains in horsepower and torque.  

Overall, you must understand that catless downpipes may not be permitted in some areas, so we produce both versions of the same downpipe at Palenon Performance.

FAQs

Do the BMW B48 catless downpipe and the catted downpipe have major differences?

Yes, the main difference is the catalytic converter. Catless downpipes remove it so that it can have increased performance but potential emissions issues. But catted downpipes retain the catalytic converter, maintaining emissions compliance while still offering performance gains.

Can a BMW/Supra B48 downpipe fit a B46?

No. It is technically impossible to fit a B48 downpipe on a B46 engine. The b48 is the EURO version, and the B46 is the US version. This is the reason we have produced separate downpipes to fit the exact models. You can purchase the required downpipe in catted and catless type.

How much horsepower can a high-flow downpipe add to a B46/48 engine?

On average, a high-flow downpipe can add about 16-20 horsepower to a B46/B48 engine. This is due to adding more exhaust flow and reducing back pressure. The actual gains may vary depending on other modifications and the specific tuning of the vehicle.
