What made you choose this particular product?
it was a gift for high school graduation from my uncle, i've been wanting a flowmaster for quite some time, so finally having one made me happy.
Is this your first time buying from this brand? Did you consider other brands?
yes, having never put an exhaust on any car that i or my family has owned, flowmaster had the best sound to make my 4.0 more noisy without being obnoxious
Was it easy to install? Any installation tips that will help others?
did require cutting and welding

What made you choose this particular product?
Super 40'soft sound amazing...but drone makes them not family or neighbour friendly.
Is this your first time buying from this brand? Did you consider other brands?
Yes. I have used magna flow in the past, better for longer drives but not as nasty sounding...and I mean nasty in a good way!

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
