Check My VINUnlock the full potential of your B58-powered BMW or A90/A91 Toyota Supra with our catless downpipe, engineered for maximum flow and an unmistakable growl. Ditch the factory catalytic restriction and let your turbo breathe the way it was meant to.
Why you'll love it
- High-flow, catless design that cuts backpressure and wakes up spool
- Mandrel-bent construction for smooth, uninterrupted airflow
- Direct bolt-on fit using factory mounting points, no cutting required
- Deep, aggressive exhaust tone without drone at cruise
- Built for track and street use on Gen 1 & Gen 2 B58 platforms and the A90/A91 Supra
Real Gains, Not Just Noise
Less backpressure means your turbo spools quicker and your engine breathes easier, translating to a noticeably stronger pull through the rev range. Add a proper tune on top and you're looking at real, meaningful gains in horsepower and torque, not just a louder exhaust note.
