Show original supplier description
The Flashark Exhaust Downpipes Test Pipes are engineered to replace the restrictive factory catalytic converters on your 2003-2007 Nissan 350Z (Z33 Chassis) with the VQ35DE engine, significantly improving exhaust flow and boosting horsepower. The TIG-welded joints prevent cracking, while CNC-machined flanges ensure maximum strength and durability. A mirror polish surface and chrome-plated flanges add corrosion resistance. Installation involves bolting these test pipes directly to your existing exhaust system, typically used in track and high-performance applications. This modification can lead to noticeable gains in horsepower and torque, enhancing overall engine performance. By removing the catalytic converters, these pipes also reduce the risk of clogging or failure, potentially lowering long-term maintenance costs. This product is designed for the 2003-2007 Nissan 350Z and also fits the Infiniti G35. It is important to note that while this product is intended for off-road and high-performance use, installing it may trigger a check engine light due to the removal of catalytic converters. Users may need an O2 spacer or a tuner to disable rear cat monitors.
