Smooth driveability and reliability depend on having a driveshaft and universal joints in good working order. A Mustang's driveline is something you want to know is there without being able to feel it.
When the driveshaft and universal joints, or U-joints, are felt and heard, it's usually bad news. These quality, replacement style universal joints connect your fox body Mustang's driveshaft to the rear end pinion yoke and will get your driveshaft turning smoothly again. Sold as each.
LMR is a great company with great products. I recently purchased the Gibson Catback exhaust for my 2015 Mustang Ecoboost and I love it. Easy to install, great looking tips, and best of all almost half the price than competitors systems. My main reason I decided to go with Gibson was because off the reputation and because I think after searching all the exhaust systems, their exhaust system is probably the best sounding one. No raspyNess what so ever you expect from a 4 cylinder exhaust system. It's a nice low, deep tone.
