Product Overview

Borla offers 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 austenitic aircraft grade stainless steel 2-1/4 system features a H-Pipe for increased performance and improved sound. The system splits from the converter into a dual rear exit with large 4" polished T-304 stainless steel, 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. Borla Performance Industries has a 40-year tradition of building great sounding performance exhaust from CNC mandrel bent high quality, T-304 austenitic stainless steel that is superior to T-409 or aluminized steel. The high quality of this marque demands Borla exhaust, where Performance is our middle name. And, all genuine Borla street exhaust systems are backed by an unbeatable million-mile warranty.
