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!

Joey Kaiser

1994 Ford Mustang

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

What made you choose this particular product?

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
