[More Info]
This Flowmaster Force II® cat-back exhaust system is custom designed for 1996-1999 Chevrolet Tahoe/GMC Yukon with 5.7L engine and is perfect for the person looking for a mild to moderate sound level inside and outside of the truck, with all of the performance benefits that you would expect from Flowmaster®. This bolt-on emissions-legal system features a flanged inlet with dual pipes flowing into a Scavenger Series Y-pipe for maximum scavenging and torque gains as it transitions into the large 3.00-inch mandrel-bent aluminized steel inlet pipe flowing into a 50 Series Big Block™ muffler for a deep mellow tone. The single 3.00-inch aluminized steel mandrel-bent tailpipe is finished off with a turndown style tip that exits behind the right rear wheel and uses the factory hanger locations. The exhaust system is covered by our 3-year Limited Warranty and includes all necessary parts and hardware for a quick and easy installation you can do at home. Notes: Fits 2/4 wheel drive models with 4 doors only.
