The Greddy Ti-C is Greddy's only single exit exhaust designed for the 350Z. I bought it with weight savings, sportier sound, and a minor power increase in mind. Not long after I got it, I had the resonator removed to improve the tone, flow characteristics, and ground clearance since it was lower than the stock "D" shaped resonator. It has a great sound and is far lighter than the stock exhaust. As with most minor NA bolt-ons, the power increase is minimal without additional mods and a tune.
