Product Description

NOT CARB LEGAL.  CAN NOT BE SHIPPED TO CALIFORNIA.  RACE USE ONLY!

The AMS "Widemouth" Downpipe for the EVO X is the best power producing system available on the market. Using a CAD designed cast O2 housing with Flex Piping and Cast-end AMS was able to obtain the perfect fit and specs they required.

The Problem:

The turbine outlet on the OE EVO X turbo is a cast piece that hugs the back of the turbo and has a small diameter outlet, necking down to around 2.25” before it enters the actual downpipe. The discharge from the turbo’s internal wastegate is introduced right at the point where the exhaust flow exits the turbine and the entire gas flow is then forced to make a tight turn all in a small area. This creates a lot of turbulence especially when running other power increasing mods.

The Solution:
By casting the turbine outlet section, AMS was able to maximize the tight space allowed for the O2 housing and downpipe. CAD designed in three dimensions, the downpipe can handle a higher volume and creates a straighter path for the exhaust flow. This design ensures the ideal performance for anything from the OE to any aftermarket turbo in the market today.


The AMS downpipe is completely made of 304 cast stainless steel, including the flex pipe and flanges. Precise fitment is guaranateed and makes for easy installation given all the gaskets and hardware provided. AMS even incorporated a bung for a wideband gauge with a plug included, ensuring this would be the one and only down-pipe you'll ever need!
