Stillen 504355 Dual Exuast System 09+ Nissan 370Z
STILLEN is proud to offer the complete, true dual, stainless steel exhaust system for the NISSAN 370Z. Constructed out of polished stainless steel and finished with 4.5" polished 304 stainless tips and polished mufflers this exhaust nets a gain of 18 rear wheel horsepower!
With years of experience on the VQ35 engines STILLEN was able to utilize that knowledge with the larger 3.7 liter and find hidden power in the factory exhaust system.
In years past, magazines have always shown the STILLEN exhaust to be the most powerful exhaust when tested in their comparison shootouts. Constantly remarking on the superior construction, perfect fit and finish and attention to detail. With a sound that offers an aggressive, yet refined note that does not disturb the senses or drone inside the vehicle.
