Active Autowerke B48 Downpipe Exhaust Upgrade Toyota Supra 2021+

In 2012, Toyota approached BMW with a proposal for a joint development effort for a new sports car that would replace the venerable and beloved Supra MK4 which was retired from production in 2002. After several years of design, development and testing, the Toyota Supra MKV was launched in 2019 to mixed reviews but everyone agreed that it was a balanced drivers car.

Toyota and BMW choose to use the B48 inline 6 cylinder engine, a valvetronic, single turbo version of its direct-injection engine. The Active Autowerke Supra MKV catted downpipe helps unleash some of the potential that is restricted by the OEM downpipe.

The dyno chart shows an increase of 18 whp using the Active catted downpipe and signature exhaust with the stock tune. Turbochargers are powered by spent exhaust gases created during the combustion process. The quicker these gases are evacuated, the better. Unfortunately, the factory down pipe in the B48 is quite restrictive, which results in slower exhaust gases and slower turbo spool.

The Active Autowerke Supra MKV Signature down pipe utilizes stainless steel piping in order to provide more power, quicker spool, and extreme durability.

Features:

• NO CEL when using this downpipe
• Quicker turbo spool
• Can reach operational efficiency within 9 seconds of startup
• Easily bolts-on no cutting or welding required
• Durable construction from TIG welded 304 stainless steel
• Ultra high flow 400 cell per square inch catalyst
• 304 stainless steel substrate is furnace braised to the mantle for outstanding durability
• Made in USA
