What made you choose this particular product?
I wanted my muscle car to sound like a muscle car.
Is this your first time buying from this brand? Did you consider other brands?
I previously ordered a Dynomax exhaust and waited 4 months, however it was out of stock.
Was it easy to install? Any installation tips that will help others?
Hatch tire and Auto installed it.
Once you've had a chance to use the product, did it meet your expectations?
I just had it installed. There is a bit more drone, but that is to be expected if you want that deeper tone.
