Overview

The Irish Racing cat-back exhaust system is a free-flow, bolt-on direct replacement designed for the BMW E30 325i and 325ix.

Constructed from 100% polished 304 stainless steel, this system offers a weight savings of over 10 pounds compared to the stock unit. It produces a slightly louder, throaty sound under acceleration and remains quiet at cruising speeds, avoiding unwanted harmonics.
Show original supplier description
The Irish Racing cat-back exhaust system is engineered as a direct, bolt-on replacement for the BMW E30 325i and 325ix models, utilizing factory hanger locations for straightforward installation. Constructed entirely from 100% polished 304 stainless steel, this free-flow exhaust system not only enhances your vehicle's sound profile with a throaty note during acceleration and no drone at cruising speeds, but also contributes to performance gains. It offers a weight savings of over 10 pounds compared to the original stock system. This exhaust system includes all necessary hardware for installation, such as flange bolts, a rubber mounting donut, and donut flanges. Note: While this system can be fitted to the 'e' model E30, a Y-connection will need to be fabricated due to the difference in the center pipe configuration (single pipe for 'e' models vs. dual pipes for 'i' models).
