Product Description

The MBRP S49033BE cat-back exhaust system is a performance-oriented upgrade engineered for the 2022-2025 Honda Civic Si and 2023-2025 Acura Integra with 1.5L turbocharged engines. Built from high-grade T304 stainless steel with mandrel-bent tubing, this exhaust improves airflow over the factory system, which can enhance throttle response, mid-range power delivery, and overall engine efficiency while maintaining a balanced street sound profile. Its dual rear exit and distinctive burnt 4.5" tips bring a more aggressive look and deeper exhaust note without excessive drone on everyday drives.

Designed as a direct bolt-on system with no cutting required, installation is straightforward and retains OEM-like fitment. The Street sound profile offers a moderate increase in exhaust volume that is engaging without being overpowering, making it suitable for daily driving or spirited weekend use. Backed by MBRP's lifetime limited warranty, this cat-back exhaust delivers both style and performance for compact sport enthusiasts.
