This 2.5” ID, 6” long flex-coupler is designed for upgraded exhaust systems in 5VZ 3.4L engine swaps. Featuring durable stainless-steel braiding, it provides flexibility and vibration absorption to protect your exhaust components. Intended for welding installation, it fits seamlessly into a 2.5” exhaust setup and is highly recommended when using the 3.4L Conversion Crossover Pipe or exhaust headers. Install it downstream of the exhaust collector, near the catalytic converter, to ensure optimal exhaust flow and system longevity.
