Description

This Force II® system is specifically designed for 1986-1990 Chevrolet Corvette's with the 5.7L engine. The system starts at the factory ball flange at the rear of the car flowing into a Scavenger Series® Y-collector splitting the system into duals. The 2.50-inch mandrel-bent aluminized steel tubing flows into a pair of specially designed 60 Series™ Delta Flow® mufflers keeping the interior tone down to a minimum, with a deep mellow performance exterior tone. The system is finished off with dual 2.50-inch brushed stainless steel tips on each muffler and uses the factory hanger locations making installation a breeze. Force II systems deliver a moderate exterior tone and a mild interior tone, and are suited to customers looking for efficiency improvements without a lot of interior noise. Like all Flowmaster® systems, the benefits include improved throttle response, power and mileage. Designed for an easy fit, these systems include all necessary parts and hardware for easy installation.
