Product Description
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 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.

Nice quality exhaust. It frees up some power and sounds good- not too loud when you want it quiet, but it opens up nicely under load. If you are going to use it on track or ever have to remove it to work on anything else- plan ahead and upgrade to Z1 metal gaskets between the cats and y-pipe and between the y-pipe and mid pipe. My stock gasket between the y-pipe and mid pipe split the first time I separated the two.
I have had this exhaust for almost 2 years and it has held up well. The tips are still shiny. Some light surface discoloration has finally appeared on the face of the cans, but it is probably due in part to all the salt we use here in the winter and I imagine it would clean up easily with the right product. It is also on the top section so not very noticeable from behind.
