5 Stars   Just the sound I was looking for

On start up the exhaust isn't very loud. But once you tap the gas the car roars. Definitely a loud exhaust with a stock H pipe. Has a very tame idle and you can drive it without waking up the neighbors. It's pretty quiet inside the car. A decent amount of drone at around 1800-2k but nothing crazy. Overall I LOVE this Catback and will most likely be buying an off-road X to complement it. It also shipped in 2 days! Thank you LMR!

5 Stars   Nothing Beats BORLA!

Like everything else, you get what you pay for! I had cheap Flowmaster 10 series mufflers before this Borla cat-back set-up! They were OK for the price and all, but sounded like every other muscle car and truck on the road! This Borla cat-back sets your Mustang apart from the rest! It is on the pricy side, but remember, you always get what you pay for! It has a deep, beautiful tone with absolutely ZERO drone on stock gears and stock mid-pipe, but I have upgraded both since I have purchased this cat-back. Highly recommend this cat-back!!! No regrets!!!

Image uploaded by Tyler R. Replaced my cheap catback with this Borla catback and never looked back. The kit was a perfect fit and the exhaust tips sit perfectly to display the Borla logo. The exhaust tone is MUCH deeper and throatier. The car actually sounds like a muscle car and it feels much more responsive.
