    Purchased these 3" HFC's to add to my MAK race pipes for my 2016 Ford Mustang GT that was running the Borla S-Type axel back with SR X pipe. Tone and volume increased by 30% and was exactly where I wanted to be so very happy with the upgrade and seller was awesome to work with as for communication and product support!
