Product details
Replace the corresponding secondary catalyst section with stainless bypass downpipes on the confirmed supported V8 SUV layout. These are uncatalyzed secondary pipes and do not include the separate primary HJS catalyst assemblies. Fabspeed Motorsport, based in Fort Washington, Pennsylvania, develops exhaust systems, air intakes and ECU tuning for sports cars including Porsche. Its development work uses dynamometer testing, road evaluation and racetrack testing.
Before you order
