STILLEN has developed a new Cat-Back Exhaust System for the 2008 Infiniti G37.

STILLEN\'s Cat-Back Exhaust System helps drum up substantial horsepower and torque, giving your G37 the extra edge of performance. This Cat-Back Exhaust System is a true Cat-Back System, and is crafted of Mandrel-bent Stainless Steel for a long service life. At idle the STILLEN Exhaust is unobtrusive, however when pressed, STILLEN\'s recognizable, trademark sound emanates. This is a pleasing tone, authoritative and yet responsible. Not only does this exhaust system have a sharp, show ready look, but it also offers impressive horsepower and torque gains as well as a lifetime warranty and is easy to install.

STILLEN\'s Cat-Back Exhaust for the 08 G37 is built for power. Power that you can feel across the power band with a big gain on top. Mileage gains during highway travel can be expected as you cruise at steady speeds. The free flowing performance mufflers and tips are made out of polished stainless steel for long life. The Stillen fit and finish is second to none. The improved airflow created by the addition of the exhaust is verified by the significant dyno HP increase.
