Product Description

The Borla 14276 S-Type Cat-Back Exhaust System is engineered specifically for the 1978-1982 Porsche 928 equipped with the 4.5L V8 engine and rear-wheel drive. Designed to replace the factory exhaust from the flange back, this premium performance exhaust uses mandrel-bent T-304 stainless steel tubing and straight-through mufflers to improve exhaust flow and throttle response. The S-Type tuning delivers a rich, aggressive tone that enhances your Porsche's performance character without excessive interior drone.

Featuring dual 2.5" polished round intercooled tips with a dual left rear exit, the 14276 adds both visual appeal and a distinctive exhaust note that complements the 928's classic performance profile. Precision CNC construction ensures a precise fit, and the system includes all necessary connecting pipes, mufflers, hardware, and clamps for a bolt-on installation. Backed by Borla's Million-Mile Warranty, this exhaust system elevates both sound and performance for your Porsche 928 throughout the 1978-1982 model years.
