What made you choose this particular product?

It’s definitely louder but not too loud to where it’s annoying driving around

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

Yes but flowmaster had the best sounding in my opinion and was all metal

They cut out the old one and put in the new in a few minutes

Brett Moffett

1995 Ford Mustang

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.
