Flowmaster 817670 - Force II Cat Back System

About this product

Flowmaster's Force II Cat-back system for the 1992-1996 Chevrolet Corvette is perfect for the person looking for a moderate exterior and mild interior exhaust tone, with all of the performance benefits that you would expect from Flowmaster. This bolt-on DOR (Dual Out the Rear) emissions-legal system for the 5.7L LT-1 and LT-4 engines features 2.50" 409S Stainless Steel piping and 60 Series Delta Flow mufflers. To reduce the interior sound level, the system also includes a straight through, tuned resonator assembly that attaches to the back of the factory catalytic converters. Like all of Flowmaster's systems, the pipes are all mandrel bent to provide maximum efficiency and performance. The system finishes with polished OEM style rectangular stainless steel tips. The exhaust system is covered by Flowmaster's Lifetime Limited Warranty. Designed for an easy fit, this system includes all necessary parts and hardware for installation.

3" exhaust was a must for me, flowmaster has a very good quality product and it sounds amazing

Is this your first time buying from this brand? Did you consider other brands?

Yes first time buying Flowmaster. I considered the AWE Track but it was backordered

Was it easy to install? Any installation tips that will help others?

Slightly challenging. A tight fit and you need to cut the stock exhaust in half to remove it. If you've done this kind of stuff before its super easy

Once you've had a chance to use the product, did it meet your expectations?

FAR exceeded my expectations. Sounds way better in person than in videos
