Widemouth Downpipe by AMS®. The ams "widemouth" downpipe is the most power producing and well designed downpipe on the market. After months of development and testing ams have created the best flowing downpipe possible. Using a cad designed cast O2 housing ams were able to obtain every angle ams wanted for maximum flow and perfect fitment. This product is made of high-quality materials to serve you for years to come. Designed using state-of-the-art technology and with customers in mind. It will meet your needs and deliver great quality at an affordable cost.
Material: Stainless Steel |
Inlet Diameter: 3" |

oem design leaves room for big improvements
the turbine outlet on the stock evo x turbo is a cast piece with a rather complex geometry. it hugs the back of the turbo pretty tightly 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 and if the exhaust gas volume is increased by running other power increasing mods, this juncture is an area where a lot of backpressure will be created. due to the space constraints, it is real hard to design a low backpressure fabricated tubular part to fit in the area allowed that is actually better than stock.
removing restrictive design constraints allows for maximum power
by making the turbine outlet section a casting, ams were able to maximize the tight space allowed for your o2 housing and downpipe. by using three dimensions to make a higher volume, straighter path from the turbine housing to the downpipe itself ams achieved the best exhaust flow and power increases without sacrifice. this downpipe provides more than enough flow for anything from stock to the biggest upgraded turbos available making it the last one you will ever have to buy!
better than oem quality, durability and fitment
unlike the competition, ams downpipe is completely made of 304 cast stainless steel, including the flex section and flanges, for rock-solid durability. no thin, cheap tubing that can crack over time from engine movement and give you headaches down the road. precise fitment makes for ease of installation and ams provide all of the gaskets and hardware needed. ams even incorporated a bung for a wideband gauge with a plug included.
