What made you choose this particular product?
It came installed on the car when I purchased it.
Is this your first time buying from this brand? Did you consider other brands?
First time with this brand. I would consider going to Magnaflow or Borla again, although the Flowmasters do sound amazing, they are a bit loud for normal use.
Was it easy to install? Any installation tips that will help others?
Came installed on the car, but the fit is good.
Once you've had a chance to use the product, did it meet your expectations?
These make the car sound very aggressive, you can hear the car coming from the other side of my small town. So they sound bad ass...but can be annoying for your neighbours and police.
