Review on 🏎️ Pacesetter 753505 Direct-Fit Manifold with Catalytic Converter: High-Performance Solution for Seamless Exhaust System Integration by Ryan Calabro

I had a cracked exhaust manifold and my Titan ran code p1283 related to an exhaust leak/O2 sensor. Bought this advanced exhaust manifold and was surprised that the manifold was bent at an angle compared to the original which was 90 degrees. The curved angle allows for a more efficient and less turbulent flow compared to the original factory exhaust manifold. To install the drive manifold, I removed the steering axle and in addition raised the motor while it was resting on a piece of 2x4 wood. I then raised the engine about 1+ inch to make room to remove the exhaust manifold. After installation I did a factory reset to have the fuel ratio calibrated to adjust the fuel/air ratio. Gas mileage has improved and now the truck is working like a beast.
