Used Front Pipe Exhaust 1990–2019

The front pipe, or downpipe, connects the exhaust manifold or turbo outlet to the catalytic converter. It handles the hottest exhaust gases in the system and is the first section most likely to develop cracks or leaks. On turbocharged engines, the front pipe is part of the turbo-back exhaust path and directly affects performance. We list 14 used Front Pipe Exhaust from 4 sellers covering 10 makes. Frequently stocked brands include Chevrolet, Honda, Lexus, Infiniti, Mercedes Benz. Front pipes take a beating from heat cycles, so inspect any used unit carefully. Look for cracking at the flange welds, thinning at bends, and check inside for heavy scaling that narrows the pipe diameter. Flex joints should still flex without binding. On turbo vehicles, confirm the pipe diameter matches your turbo outlet. Filter by your vehicle and engine to find a front pipe exhaust that bolts up correctly. These vary a lot between engine sizes and turbo vs. naturally aspirated configurations.
