What made you choose this particular product?
Got these for a deal of a GT in the local junkyard. Cheap and had everything I needed to fit to my car.
Is this your first time buying from this brand? Did you consider other brands?
Yes, but my dad has had Flowmasters before so between that and their excellent reputation I knew they were for me.
Was it easy to install? Any installation tips that will help others?
Somewhat difficult. Passenger side pipe would not go in the car even after loosening the shock mounts and letting it droop from the control arms. It had to be cut and welded in the car
Once you've had a chance to use the product, did it meet your expectations?
Yes, sounded excellent especially for a V6

Wanted to try the single chamber muffler out
Is this your first time buying from this brand? Did you consider other brands?
No as I've always purchased Flowmaster
Once you've had a chance to use the product, did it meet your expectations?
Priced as usual for Flowmaster and I must say it's something you must experience yourself

What made you choose this particular product?
Sounded the best in my opinion. Very nice burble with stock exhaust manifolds and reasonable volume when you wind out the car. Just had a great muscle car sound in my opinion.
