For this PLM Integra/Civic mid pipe exhaust, we eliminate both factory restrictive resonators and replace it with a high flow resonator right after the front pipe connection, with mandrel bend 3-inch tubing, y-pipe collector, and hand TIG welded.
This mid-pipe exhaust kit definitely free up all the horsepower you get from the 1.5L turbo engines and is one of the best upgrades for your 2023+ Integra or 2022+ Civic!
Installation Note: Because the passenger side factory muffler does not have a flange connection, it will need to be a "cut & clamp" installation. No welding is needed!
