Exhausts

MAKE YOUR VQ NOTICEABLE – EXHAUST

An upgraded exhaust is another 350Z modification that requires some thought. Like pretty much every other 350Z mod, there are tons of aftermarket options out there for the Z33 chassis. There are three main considerations to take into account: price, sound, and performance. Cat-back exhausts are without question the most common type of exhaust fitted to lightly modified Zs. Cat-back exhausts are exactly what they sound like. They replace all of the factory exhaust components from the catalytic converter to the exhaust tip. This type of exhaust is generally made of stainless steel to improve exhaust gas flow out of the engine, resulting in a bit more power and a lot more noise. Aftermarket cat-back systems can vary a lot in terms of their pipe diameter, tip diameter, and how they exit the vehicle. Some aftermarket 350Z exhausts are single-exit, but the vast majority are dual-exit like the stock exhaust. The sound produced by an aftermarket 350Z exhaust heavily depends on the diameter of the exhaust piping and the type of muffler it employs. Better exhaust flow resulting in more power/torque, 10-20 horsepower / 10-25 lb-ft of torque gain, better exhaust tone, and improved exhaust aesthetics.
