There are limited aftermarket upgrades for my Infiniti FX50S, especially when it comes to a bolt up cat-back exhaust system. Borla came through with an excellent system, using the multi-core series muffler which adds an aggressive tone without being too blatant (like the Sport or ATAK series mufflers). The fit is near perfect, total install time was under 2 hours. Very happy with the Borla brand & sound.

I wanted a deeper, more mellow sound for my V8, but didn't want the noise to be too loud. Borla is exactly the sound I was looking for.
