The AMS EVO X "Widemouth" downpipe is the highest power producing and well designed downpipe on the market. After months of development and testing we have created the best flowing downpipe possible. Using a CAD designed cast o2 housing we were able to obtain every angle we wanted for perfect fitment and flow.
Our downpipe is completely made of 304 stainless steel including both flanges and includes a bung for a wideband gauge with a plug included.
