IRL G8X S58 Downpipes

Upgrade your vehicle's performance with IRL LLC downpipes, which alleviate back pressure from stock catalytic converters. By switching to our downpipes, your turbos will spool faster and reach peak power. A tuned S58 can see a 30HP boost with stock turbos. The flex pipe section reduces strain and vibrations caused by the downpipes. Other features include smooth bends for optimal airflow and a recommended professional installation.
