Borla Performance Industries is proud to announce the release of two Cat-Back systems for the much-touted Infiniti G35 luxury sports cars -- part #140093 for the sedan and part #140057 for the 2-door. Both systems are based on Borla?s incredibly successful program for the 350Z; add a Borla header (part #17221) for the look, sound and feel of total performance. The high quality T-304 aircraft grade stainless steel 2-1/4 " system splits from the converter into a dual rear exit with large 4" polished, logo embossed tips. Weighing in at more than 20 pounds lighter than the factory system, tests show an exciting 45% increase in flow! Borla?s strong heritage of building high performance exhaust for Nissan models dates back to the early Z cars. Borla?s race-bred technology has been transferred from many years of successful race programs, learning to make it light, make it last and make it perform, making Borla a natural for the Infiniti G35 -- great power, super lightweight while being ultra brawny stainless steel, sexy powerful look and a great strong sound. All you?ve come to expect from Borla, the most winning exhaust in racing. Isn?t it about time you stepped up to Borla? Borla Performance Industries has a 30-year tradition of building great sounding performance exhaust from CNC mandrel bent high quality, T-304 stainless steel that is superior to T-409 or aluminized steel.
