"Taking off the old exhaust and installing the mufflers was a breeze. Not so easy with the tail pipes though. Had the jacks on 2 blocks of wood and still couldn't get the right angle to install them. My mechanic did it real quick once it was on a lift. Sounds awesome, but has some drone." —Jason O from Chapel Hill, NC bought a Flowmaster Exhaust Systems for a 1999 Ford Mustang, GT, 4.6L V8.
"I'm slowly modifying a 99 Cobra convertible. I recently bought a Borla ATAK cat-back system. I have to say the sound and additional power has transformed my 13 year old Cobra. The sound is incredible, the best on the market. Yes it is pretty loud when you have a heavy foot, but when you drive it easy it's fairly tame. The fit and finish of my Borla exhaust is second to none. I highly recommend a Borla system!" —Joe M from Monument, CO bought a Borla Exhaust Systems for a 1999 Ford Mustang, Cobra, 4.6L V8.
"The install wasn't too bad my old exhaust didn't want to come off so we had to cut it out which took some time. Everything fits and sounds great." —Danny G from Timonium, MD bought a Flowmaster Exhaust Systems for a 1999 Ford Mustang, GT, 4.6L V8.
