High-Flow Catless Downpipe For Toyota Supra MK5 (A90/A91 B58) – OPF Delete

 

The MK5 Toyota Supra (A90/A91) with its formidable BMW-sourced B58 engine is a modern legend, but its full potential is restricted by factory emission components.

 

Our high-flow catless downpipe for Toyota Supra MK5 helps you eliminate this bottleneck and unlock significant horsepower and torque gains, as well as an improved turbo spool and a truly aggressive exhaust note. This premium Supra A90 B58 Catless Downpipe is a direct replacement for the restrictive OEM catalytic converter and, crucially, the Otto Particulate Filter (OPF) found on many U.K., EU, and U.S models.

 

Crafted from durable T-304 stainless steel with precision mandrel bends, engineered for maximum flow and resistance to corrosion, even under extreme conditions.

 

Grab this today, and experience immediate throttle response, reduced turbo lag, and the authentic roar of your B58 engine.

 

What You Get Here:

  • Maximum Performance Gains: By eliminating the factory catalytic converter and OPF, this downpipe significantly reduces back pressure, leading to substantial increases in horsepower and torque.
  • Faster Turbo Spool: Improved exhaust gas flow means your B58’s turbo spools up quicker, providing more immediate power delivery and reducing turbo lag.
  • Aggressive Exhaust Note: Transform your Supra’s sound into a deeper, more pronounced, and truly performance-oriented roar that perfectly complements the B58 engine.
  • Direct Bolt-On Fitment: Engineered for a precise and straightforward installation as a direct replacement for your OEM downpipe on the Supra A90/A91 MK5 B58.
  • Integrated Heat Shielding: Features robust construction that helps manage under-hood temperatures with its integrated shield.

 

Fitment:

  • Make: Toyota
  • Model: Supra MK5 (A90 / A91 Chassis)
  • Years: 2019+
  • Engine Code: B58 (3.0L Turbo I6)
  • Note: Fits both 3.0L and 3.0L (HP) versions of the B58 engine.

Really helpful staff. Car had its belt done here, and when i needed advice, they were so helpful. It wasn't my belt. It was another issue. But thank you for being so helpful, so I appreciate it.

Great stock of nippon spares. Came quite in handy for last Skyline replacement.  Delivery took about 6 days to get to me in Dublin. Would 100% recommend.

My son’s car had had a diagnostic elsewhere. It needed a new turbo and after speaking to Josh I felt confident that he would do a good job. He arranged recovery and called me with updates about the car. Absolutely brilliant customer service and very honest.
