Introducing Boost Logic’s A90 Supra Single Exit Titanium Exhaust, meticulously crafted for unparalleled performance and unmistakable JDM sound. Our 1-2-1 configuration is precision-engineered to optimize exhaust flow, echoing the iconic roar of the legendary 2JZ Supras. At the heart of our design is a 4″ pipe, meticulously honed to ensure maximum airflow. This stream then bifurcates into dual 3″ pipes, deftly accommodating the under-chassis brace without compromise. Finally, the exhaust converges back into a single 4″ pipe, culminating in our bespoke 4″ teardrop muffler. Entire system weighs under 20lbs! Teardrop muffler available in Polished Blue or Matte Raw finish. Optional add-ons:  4″ downpipe that mates up perfectly with our single exit exhaust for maximum exhaust flow. Exhaust Cover for the now empty hole located on the right side of your factory diffuser. When installed, this system does not utilize the OEM valve motor. However, leaving the factory valve motor unplugged will NOT trigger a check engine light on this platform; no tuning or coding is required to suppress it. Please note: due to the aggressive size of the teardrop muffler some cutting of the rear diffuser is required for optimal fit.
