Our car, the "Sector111 Type 49 Evora," has a Larini Sport Evora cat-back exhaust (you can hear the difference between this setup vs stock HERE). This exhaust has been installed and run for a few thousand miles. If the ECU was going to dial back power, it would have done it by now. Here's what we learned...
...Our Evora dyno'd at 253 rear-wheel HP & 240 lb-ft of torque. Compared with the stock Evora's 244 rear-wheel HP (based on the standard 12.5% drivetrain loss), thats an increase of just over 8HP. When you couple that with the 20 lbs of weight savings, this is a nice upgrade.
