As you might’ve seen recently from our posts on Facebook and Instagram, our Project Supra recently received a lot of new modifications, including a full turbo-back exhaust system. From our experience without BMW inline-6 engines, we knew the Supra’s B58 engine would sound great with an aftermarket exhaust and we also knew an aftermarket exhaust could massively increase power output.
The exhaust setup we chose is a combination of parts from different manufacturers. Right off the back of the turbocharger, we replaced the very restrictive OEM downpipe with a high flow downpipe from Armytrix. Moving to the catback section, we replaced everything with an HKS catback.
Compared to stock, the HKS catback isn’t much louder, however, when paired with the Armytrix downpipe, this setup sounds incredible! With this exhaust setup, the pops and bangs from our VR Tuned ECU flash are made even louder, resulting in a wild sounding exhaust.
With our VR Tuned ECU flash, we found pretty big power gains while still using the stock exhaust. Once the new exhaust setup was installed, we found massive low-end and mid-range power gains. The gains eventually taper off at peak RPMs, however, the low-end power gains are more important since you’ll be using low-end and mid-range RPMs when driving on the street.
