About this product

Part #: 817659

Flowmaster's Force II Cross Member Back system for the 1970-1973 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) system for the 5.7L V8 features 50 Series Delta Flow mufflers, a Scavenger X-pipe assembly and 2.25 in. tailpipes. Like all Flowmaster systems, the pipes are all mandrel bent to reduce any restrictions and maximize performance. The system finishes with rectangular polished 304S stainless steel tips that exit in the factory cutout bezels. The exhaust system is manufactured out of 409S stainless steel and is covered by Flowmaster's Lifetime Limited Warranty. Designed for an easy fit, this system includes all necessary parts and hardware for installation. Note: Can be used with manifold downpipe kits #81098 (Manual trans.) or #81095 (Auto trans.) to create a complete system.

What made you choose this particular product?
Bought mandrel bends, muffler and pipe from Jegs. Can't beat their pricing. They also sell the pre-bent Flowmaster tail pipe sections, which are worth the money.
Any additional comments?
Nice quiet muffler, what I was looking for.

What made you choose this particular product?
I chose it because it was a good value in terms of sound for the money. It was also plug and play whereas other systems required a fair bit of modification on my part and I didn't want to deal with that.
Is this your first time buying from this brand? Did you consider other brands?
This is my first time buying from them and I had considered Borla, but went with fFowmaster because of its value.
Was it easy to install? Any installation tips that will help others?
I installed it myself and it wasn't all that easy. The nut is just supposed to be removed from the bolt and the new exhaust should be bolted right back on. The thing is that my bolt was stripped and it was pressed in from the factory so it had to get pushed back out and replaced with a new bolt and nut. Other than that it was plug and play.
Once you've had a chance to use the product, did it meet your expectations?
It is definitely a good value as it gives a deeper tone while making it a bit louder, but not loud enough that it gets annoying. It also doesn't drone too bad when just driving around town.
